Came up to a Y in the trail on the MTB, and not being able to figure out whick way to go, did a low-speed forgot to unclip fall into a hole beside the trail. While going around a very pretty young lady on an uphill, had to swerve to miss her and drove the left handlebar into my left knee..nice cut. Far too many chainrings into calves to even mention...several didn't even notice until I was off the bike in the shower......
