The only mode of transportation that I have employed in the past couple years is the bicycle. The bicycle has become a healthy, alternative to the motorized vehicle, and is much funner. I am very interested in the human-powered vehicle, and have done a lot of research and tinkering with expirimental bikes. I have made a great deal of expirimental bikes, some of which I have below.
Some of the bikes I have made seem to last me a long time, even for 5 years. Parade bikes, kid bikes, all sorts. I have done a great deal of customization for the past couple of years, even been in parades for Fourth of July. One of the biggest reasons I promote bikes, however, is not for myself but for the bike trails around Arlington. I've tried to make the bicycle a 'common denominator' to all generations, common ground for communication and sharing with other people, especially the younger generations.
