I was on a mountain ride here in Colorado a few years back when I got a little too exuberant -- I was going about 45 mph when I hit a corner that was sharper than I thought, and the tires slid out from under me. I tumbled for quite a way, and when I stopped I was missing a lot of skin and my shoulder was dislocated (tore through my labrum in the front). Fortunately a nice woman stopped and took me to the emergency room (her three year old daughter told me "I only ride my bike on flat ground" which I deserved). I got off lucky, only 3 months of physical therapy. I'm more careful these days.
