Zakkalicious posts about Fear Mongering among some American cyclists. I think it was Bike Lane Hottie who wrote that cycling advocates continually gripe about how dangerous cycling is, and then wonder why nobody wants to ride a bike. Cycle Dog and I occasionally discuss this topic of ineffective advocacy over email.
Enjoy the ride and quick worrying so much about the traffic. They're not gonna hit you, and if they do it only hurts a little.
