I finally took the step of commuting to work. What is normally a 20 minute drive only took 10 extra minutes by bike. I'm at work now and I feel great... more awake than I usually am at this time in the morning. Cleaning up once I got in (sweaty, smelly, dirty) worked out a lot better than I had guessed it would.
It's only an 8 mile ride (one way), but it's all along busy roads. I'll take some pictures soon! I never would have done it without bike forums!
