Good call Roody. (I never did really introduce myself here)
I'm a carfree college student, and when I build my post-college life, I hope I can make it carfree, or at least very car-lite. My reasons for not wanting a car are mostly personal and cultural, not environmental in the traditional sense of the word (although I certainly see the sense in most of those reasons).
I'm riding a BMX cruiser, but I'm buying a single-speed build in about a week, and I'll modify that quite a bit during the summer. My current bike is in my signature, and my new one will be there shortly, so check them out.
My city, Columbia Missouri, is absolutely great for going carfree. Especially since my university's campus butts right up to downtown. It's fun. I think when I graduate, I may live in Hot Springs Arkansas, which is equally good for the carfree. That's the only city that is also a National Park, and I love it there.
