I was listening to some folks chat about allergy shots. They said you should wait until you are "cleared" to leave because there's a risk of anaphylactic reaction. I said, "I'm saving myself for being hit by a car," which they responded to as I expected, "You're well on your way." (The doctor speaking about allergic reaction is convinced I'm crazy in the head for all my cycling.)

This led to a conversation about the benefits of cycling, people were asking me questions, and I got to expound on how great it is to get 40 min/day exercise for a 10 min/day investment of my time (travel would take 30 min total by car).

I don't think I made any converts, but I believe what I said changed some motorists' attitudes towards cyclists on "their" roads, and gave them something to think about their own transportation. I might have planted a seed.

I don't preach unless encouraged. I view nearly anything as encouragement!
