I wish. Public transit exists here (our system even wins national awards), but it's terrible. To commute to work, for instance, would take over an hour, but I can bike the distance in under 20 minutes.

So, bike for the win!

Which, to be honest, isn't a huge lifestyle change for me anyway. I own and use a car when needed, but the bike is my primary transportation. It's faster, more convenient, and more pleasant under most circumstances.
