Hilton Head – Bike paradise?

Icon Written by elise on December 15, 2009 – 7:50 am

I recently returned from a trip to Hilton Head Island, in South Carolina. Hilton Head is located at the very south part of South Carolina, close to Savannah Georgia, and is a very popular beach vacation location. My parents, who participate in the condo swapping programs that have become popular lately, had a week to spend there and invited us to come down. I’m not usually so big on this kind of vacation, but the beach is really nice on the Island, and the kids love the beach. Plus, the island is populated with tons of bike paths, which make it theoretically easy to get around (more on that later…). So we decided to go for it.

After a very long and tiring drive, punctuated by changing a flat tire on the side of I-95, in the dark (of course) we arrived at Hilton Head. The island is built up with lots of resorts and expensive homes, grouped into “Plantations” – really just a fancy southern name for parts of the island. Maybe it had to do with the original plantations on the island back in colonial days, I’m not sure. Now, each Plantation has it’s own cache and level on the hierarchy of perceived wealth. The resort where we were staying is owned by the Mariott group, and was located in the exclusive “Sea Pines” Plantation. To access this Plantation, you must go through the guard checkpoint, where the guards collect $5 from you if you are not a “guest” and enforce a cadre of rules designed to enhance the exclusivity of the place at the expense of common sense. I think they just don’t like anything that does not conform to the aura they want to project.

For example, we brought along with us a sit-on-top kayak, in case we wanted to explore some of the area via water (it is an island after all). Well, apparently, the Sea Pines homeowners have a prohibition against any kayaks or surfboards being “displayed” in the open, on top of a car, etc. They are supposed to be kept in a building out of view at all times. The guard at the gate determined by sight that our kayak was too big for our resort to handle, and almost didn’t let us through the gate (what were we supposed to do with the kayak?). But after lengthy argument, he agreed to let us go to our resort and see if they could find a place to store the kayak out of site. They did (fortunately, the Mariott people were very helpful and accomodating) and sure enough, the guard’s supervisor came to check on us 15 minutes later, just in case we decided to ignore this prohibition.

Anyway, I’m digressing, because after that original incident, the rest of the vacation was actually pretty nice.

So, since we had all 3 children with us, we decided to bring the Madsen bike to transport the smaller ones, and my older (5-yr-old) daughter’s kids bike, and a third bike to get everyone around. While the roads on the island are narrow, there is actually a very good network of separated bike paths that run along the sides of the roads, so you can get from your accommodation to the beach and back via bike.

Because of this network of paths, a large industry of rental bikes has been built up, and many people rent bikes for the week. Most of these are beach cruisers with one speed (the island is totally flat, the only hill being the bridge over the inlet) and appear to be fairly low quality bikes. I discovered the reason for this right away, when we rode past a rental place with a sign “$20 rental for one week”. Now, the last time I rented a bike was when I was in Moab, Utah, and rented a mountain bike. It cost me $40 for ONE DAY. Similarly, a bike rental in Boston, to get around the city, cost even more than this. So obviously if you only pay $20 for an entire week, you get what you pay for.

Well, we did quite a bit of riding while we were there, in fact we didn’t use the car at all (except to go to the tire place to buy a new set of tires that is!). My daughter could easily ride safely on the separated bike paths, and we didn’t have to worry about her getting caught up in traffic. She rode over to the Children’s museum and back with her grandparents, rode to the beach, even rode ON the beach. Riding on the beach is very easy and fun when the tide is low. The beach there is very flat, which makes for great sand for riding, and you can go the whole length of the island, several miles.

One day we all took the trails and rode up to the harbor, where there are lots of yachts, (many of which are very, very large), a great playground, and some little shops and restaurants. We took a round-about way on the way back, having to stop and examine the bike path signs that are dotted around the intersections here and there. The signs were a good thing, because it was pretty easy to get lost with everything looking the same (the uniformity mantra works!).  In fact, I was not sure we were on a different path until we rode past what appeared to be a heritage vegetable farm, which I didn’t remember from the way out. Hmmmm… well, it was a nice day and we weren’t in a hurry.

Occasionally while riding, we would go past a little “borrow pit”, where we spotted some small alligators. (I wonder where they take them when they get too big?). A borrow pit is where they’ve borrowed some soil to fill in another place, such as where the road is. It’s common in areas that were swamps and wetlands at one time. They just move the dirt around and make them ponds and berms – easier to travel around. The kids all enjoyed seeing the alligators and the herons. We never saw the alligators move much. They have a way of making you wonder if they really are alive….just so you might come a little bit closer….and closer….

As we rode around, we encountered many other people on bikes, some of which probably did not ride a bike except for once a year, at Hilton Head. This was evidenced by several near-crashes I witnessed involving curbs and pilot error. One couple almost colliding with each other while getting started. I thought the fact that these people were even out on bikes was pretty cool though, because here is an opportunity to see that one can actually get around by bike. How great! The side paths really were important in making people feel safe to ride a bike and not have to deal with traffic. It was obvious that the investment the Island had made in bike paths really did help people get around while they were on their vacations, and hopefully relieve some traffic and parking problems at the beach.

But at the same time there were some gaping holes in the infrastructure when it came to actually using the bike to go anywhere except the beach. This was especially true because if you had to go somewhere there wasn’t a bike path, the roads themselves were very busy, narrow, and populated by heavily traffic.

For example, we decided to go one day to get some Gelato at a great little Gelato place called Pino Gelato. The Gelato place is in a strip mall Hilton Head style – that is, the stores are arranged in a semi-circle, and there are trees in the parking lot. It’s on the north side of the main highway that transverses the island. The bike path is on the south side of this highway (no path on the north side). Fortunately, there was a stop light at the entrance. But to cross at this stop light required navigating a 4 lane highway with right and left turn lanes and turn arrows, no crosswalk or pedestrian signals. We had the Madsen bike with the 2 little kids in back, my 5-year old on her little bike, and 3 other bikes. We decided the best strategy was to cross en-masse, so we waited for the cross light to change, and then walked our bikes quickly across 8 lanes, avoiding right and left turning traffic. At least we were a highly visible group all together. It was not an easy crossing, but everyone made it safely and had their gelato. Of course we had to repeat this in the opposite direction.

The thing about it that was most annoying was there was absolutely no provision for any kind of crossing at that light. So if you were a pedestrian, you would also face a pretty big risk just getting across the street. And once across there is no shoulder, sidewalk, or any other way to travel down that side of the street if you needed to go to the next establishment, for example. The way it is set up, the only way to easily access any business on the north side of the road is by car.

More Beach Riding

The other time we ran into a similar issue, although this was not quite as bad, was our trip to the grocery store. With the Madsen, we were able to do this easily without the use of the car because it is SO easy to load that bike. (Take grocery sacks out of grocery cart, pile in the bucket, return grocery cart, off you go!). Again, there was no way to access the grocery store strip mall except for traditional car routes, so we negotiated traffic and a convoluted parking lot with a lot of cars backing out of spaces, turning, etc. There was actually a small bike rack at the grocery store (better than I’ve seen in many places!). This traffic negotiation was not a big deal for us, having ridden in traffic a lot and being very comfortable with it. But for these people who can barely negotiate the ramp up the curb to the bike path, there is no way they would ever access this store by bike.

The other strange thing I found about the bike infrastructure was that there was a lack of bicycle racks at the public access points to the beach (also a lack of car parking). As you approach the public access point, there are signs on every fence stating that bikes locked there will be removed. But I didn’t see any actual legitimate place to park your bike. I guess you are supposed to take it with you onto the beach? I think this has more to do with this idea of exclusivity and keeping the “rif-raf” at bay. Don’t provide any parking of any kind, and this discourages beach use except for the people who have actually paid for ocean-front accommodation.

So, overall, my reaction to biking on Hilton Head island was mixed. On the one hand, the island has a great network of paths to get you around most of the places you need to go. There are periodic signs that show you a map of the network and the island so you know where you are. And the paths encourage bike use by many, many people who would otherwise be driving around and clogging up the streets even more than they are.

But on the other hand, the infrastructure falls short when it comes to using the bike as an alternative to the car for practical purposes, such as groceries, or even other shopping. Those parts of the island are still heavily dominated by the car/strip-mall pattern of development, although with a flair to make it seem not so ugly. I found this to be a disappointment, because with just a few changes, it would be possible to greatly expand the way people could get around.

Because you have to have a sunset photo in any discussion of the beach!

But at any rate, I still think that most cities could learn a lot from the Hilton Head model and this kind of investment in alternative transportation infrastructure would really pay off with reduced traffic and higher quality of life.



Time versus energy

Icon Written by Morgan Giddings on August 24, 2008 – 3:40 pm

Recently there was a lively discussion over on the Rootsradicals mailing list about energy usage and electric bikes. There was debate about whether it takes more energy to run a bike by electric power or leg power. While the debate was all well and good, it sidesteps the bigger picture. Biking in any form, whether by leg power, electric power, or both, is a far more energy efficient endeavor than driving a car. Depending on how it is calculated, riding a bike is equal to getting anywhere from 200 miles per gallon up to over 1,000 MPG. Even the greenest of electric cars aren’t going to approach those numbers anytime soon.

But there is a tradeoff using a bike: time versus energy. The reason bikes take so little energy is because they move slowly. They don’t suffer big losses to friction (plus, they are lightweight). But riding a bike takes more time – at least to go long distances (for short intra-city trips, biking can actually be faster).

I started thinking about this tradeoff by monitoring the energy usage on my electric bike. I noticed that when I was in a hurry, I would consume almost twice as much power than when I was taking it easy and going more slowly. Now I’ve made it into kind of a game, to try to keep my energy usage down, I am also forcing myself to slow down and enjoy the ride more.

But this tradeoff is not just present in biking. It is present in nearly everything we do in “modern” society. Here are some examples:

1. The energy usage of various forms of transportation is directly proportional to speed, i.e.:
Planes > cars > trains > bikes.

2. Washing clothes and dishes – it is both faster and more energy intensive to use the washer/dryer than to do it by hand.

3. Food – it is more energy intensive to buy cheap but fast food, than to grow and cook one’s own

US society is one of extremes. On the one end we have people who jetset around in a constant aggravated rush of business. On the other extreme there are the Amish, who exemplify slow and low energy lifestyles.

And then there are all the rest of us in the middle. The question is, how much should we trade down our energy use, at the cost of spending more time on our daily activities?

I think the key is reframing that question. I linked to this article before, but I’ll link to it again because it is great – it is all about a mom who formerly led the go-go rushed life, and then due to high gas prices, was forced to slow down while becoming a bit less energy intense.

She discovered that there is increased joy in slowing down. Joy in walking the kids to school, or biking to the grocery store. Many people enjoy gardening, but think it takes “too much time”.

Maybe many of us have been convinced that we need to keep moving faster and faster to “keep up with the Joneses”. But maybe the higher cost of energy will force us all to slow down (except the super rich). And maybe, seeing our neighbors, friends, and co-workers slow down, we won’t feel so guilty about it. About taking time for ourselves, for our families, for some hobbies. Some people have already done this. I have no statistics to back this up, but I believe there is a strong grassroots movement of people doing exactly this. People who are fed up with the go-go buy-buy pace of modern life, who have slowed down, dropped out, semi-retired. Those people did it by choice. Maybe the rest of us will be forced to follow, whether we like it or not, by high energy prices.

But I don’t want to make it sound like slowing down is just drudgery. I look forward to my daily bike ride to and from work. It is a time of great enjoyment for me (except on the rare occasion I encounter an intentionally obnoxious driver). I get to look around, see the world, breath the air, hear the birds. I get exercise. I listen to music (not earphones – I have a small stereo on my handlebars). Nowadays, when I get in the car for trips around town, I actually get stressed out, whereas the bike is relaxing, just getting into the rythm of the pedals.

It is hard, though, straddling between wanting to conserve energy and wanting to keep up with all the self-imposed time pressures. Recently, after being aghast at our electric bills (definitely NOT from charging the bikes, that is only $0.03-$0.05 per charge), we realized that the dishwasher was consuming a lot of energy. So we started washing dishes by hand (with water heated by solar). This greatly reduces energy consumption. But it also takes more time. Sometimes it is actually enjoyable – just zoning out, focusing on the present moment, and even listening to music. But other times it is just stressful – because it seems like there are many other things that need to get done.

So how to find the balance? Until it is forced on us by high gas costs, I think the key is one step at a time, avoiding extremes. To me, it is all about doing the little things that are both doable and enjoyable. I’m not about to quit working just so I can farm all my own food. But at the same time, riding the bike every day, hanging the clothes out to dry, and little things like that take some time, but also save a lot of energy.

If everyone did it, there would be a huge impact on energy use and carbon dioxide production.

It is a starting point.

Taking the train

Icon Written by Morgan Giddings on June 9, 2008 – 8:39 am
Here I am in Montana near Glacier National Park, riding on one of the more fuel-efficient modes of transportation: the train. While gliding along and looking at the spectacular scenery, I couldn’t help but run some numbers through my head about the efficiency of this mode of transit.

This train is carrying 340 +/- 20 people from Chicago to Seattle, Portland, and points between. So due to my compulsive quantitative bent, I had to figure out how many miles per gallon per person this represents.

My estimate of the fuel usage is about 2,000 gallons, plus or minus 1,000. I got that estimate because I found out the Diesel tanks in the engine are 2,500 gallons, and they topped them off once for the trip (but they certainly weren’t empty). Since the train travels a total of about 2,000 miles on its journey, this represents approximately 1 gallon per mile (or mile per gallon for those who like it like that!). After I calculated that number, I talked to one of the personnel, and he said that sounded about right for fuel efficiency.

Ok, so let’s say we’re in the ballpark. In fact, let’s imagine that the fuel usage is

twice
what I estimated, just to be safe. If the train uses 2 gallons per mile, the math is easy. That means it gets 170 miles per gallon per passenger.

Let’s figure out how else we could get that kind of mileage. A bicycle would do it, but then, pedaling from Chicago to Washington state takes a while – a lot longer than the train. But the cool thing is, I have my bike with me (a folding bike that I can just carry onto the train free of charge). So I can be fuel efficient for the whole trip.

What about a Prius, the gold standard for green transportation? There are only two ways a Prius could match that mileage. One: drive really slow, like 40 miles per hour, so that the Prius gets 50-60 mpg, and carry 3 passengers and their gear. Well, you could do that, but it would take a lot longer than the train, and be a whole lot less comfortable. The other way is to carry more passengers and drive faster. Driving the prius 70 mph, a loaded prius with bikes on the roof gets at best 35 mpg (I owned one and did cross country trips with it). So, it would require carrying 5 passengers and their gear. Nope, no folding bikes are going to fit in that prius.

Well, for an airplane, fuel efficiency is right out the door. I’ve seen various estimates, but 30 MPG per passenger would be generous.

Why don’t more people use the train in the USA? Well, a couple reasons. The first is that people don’t know about it. I told several people that my family and I were doing a train trip who had no idea that there was a train to take a trip in. I guess Amtrak doesn’t advertise much.

The second is the train is perceived as slow. Well, it is slower than an airplane. But it is a whole lot more comfortable, you get to see a lot of great scenery, and enjoy the travel. But the real issue is that the US has not invested in high-speed rail like many other countries. If we had a 200mph bullet train like Europe and Japan, it would be possible to go from coast to coast within 12 hours. I’ve seen people on the internet claim that the US is too spread out for useful train service, except population dense centers. I don’t buy that. There are many large cities spread out throughout the US. If connected by high speed rail, these corridors would be used. If we just had three major east-west routes (North, middle, south) and 4-5 North-South routes, it would cover a large portion of the US, with busses acting as the local links to these stops.

While I still use airplane travel for many business trips, if practical train service were available to get me to the destination, I would use that. I like the comfort, the scenery, the ability to relax, and the fuel efficiency of the train. I just wish the US would get its act together and start building a real, large-scale rail system that shows we can once again be leaders in transportation and innovation.



Replacing two car trips per week….

Icon Written by Morgan Giddings on January 15, 2008 – 9:56 am
Recently I saw a discussion on another website about peak oil. Someone there was deriding the “environmentalists” who want us “to all use bikes”. He was saying “that is not a realistic solution”. Perhaps there is no single solution to our current mess of oil dependency. Perhaps, however, if we combine solutions, we will make a dent in this thing.

I came up with the charts below to show what would happen if 1/3 of the USA population replaced

only 2 car trips per week
with a bike trip using an electric assist bike. The bottom line is that this would
save
5.5 billion gallons of gas, prevent the release of 59 million tons of CO2 and save $17 billion dollars, keeping them in American’s pockets rather than sending them overseas.

Maybe this is just a drop in the bucket, but 5.5 billions of gas is a mighty big drop. Could 100 million Americans bike an average of 30 miles per week? It doesn’t seem like a stretch.

Here is the table on which the calculations are based:
