With "a few" years on the road as well as some off road, maybe it's the tightness of the corners and some lack of line of sight and that there can be anything from glass beading used to make the lines reflect at night (took out a friend on one dual sport ride, pretty much invisible on the pavement) and whatever other debris may be on the road, but I just can not see riding to the point where having your whole butt off the seat ,much less dragging a knee, isn't possibly using way too much of that $1 on the corner versus self preservation,. I apologize for that serious run on sentence by the way. As I said, maybe it's just the possible perils that show up on the roads in eastern Ohio and much of the rest of the Appalachian area - like a squirrel going to the other side or the random road kill in a blind corner. Even the faster guys I knew in the area didn't do that sort of stuff very often if at all. It's too easy to hit that bit of loose stuff that wouldn't be an issue otherwise. Maybe out west the roads stay cleaner. I don't know. I do know only one time have we had a guy throw his bike away and as I said, it was the glass bead build up between the car tracks after centerline painting. I was in the tire tracks, he hit the center of the lane. You couldn't see the bead in the daylight. We ride like we do because we also know we "need to go to work Monday".
