Update: I mentioned getting a bike to a friend of mine, and he told me I should get one so I can join him on RAGBRAI. If you don't know what that is, it's an annual week-long bike ride across the state of Iowa.
He did it two years ago...had a lot of fun...ended up having sex with a woman in a port-a-potty...whatever.
Anyway, I kind of want to do it. So I think I'm gonna go to a bike shop on my next day off and start training.
