I applaud your resolve.
I am getting closer to jumping into the bike commuter pool. I've finally got the light problem solved, just need fenders and a few other bits before I'm ready.
The more I think about it, the more I think I know why I want to commute. Because nobody thinks I can do it, and I love proving people wrong. I love riding my bike, and I love being "weird" and "different." It's looking like I still might not sell my car, but I'm okay with that... I'm still going to commute by bike. And I live in southern Louisiana, no reason I can't commute year-round.
I originally wanted to do it to save money, but now I just want to do it because I can.
