Its true about the consternation from the public! I was out a few nights ago to see what conditions looked like on the American River, and at an intersection some car pulled up next to me, pointed a camera at me and started in with a bunch of questions about why I was out riding in the rain. It's a bike thing, you wouldn't understand. -Wes
