This thread made me smile almost as much as a good bike ride.
This is going to sound shallow compared to the other posts. But one new reason I like riding is all the positive comments I've been getting since gas prices went up so high. Even strangers at work have come up to me and said things like, "I hear you really rock on a bike. Is it true you even ride to work in the winter? I've been thinking about doing something like that. Can you give me some pointers?"
Like I said, it's shallow, but it feels good. For years, a lot of co-workers thought I was nuts for riding my bike.
