When I was younger, I rode bareback a lot and would have the occasional fall here and there with nothing serious. In college, I was taking English horsemanship and there was no intermediate class so I was with all the beginners. One day we were working in the arena and a girl's horse spooked at the barn door swinging in the wind and instead of calmly redirecting his attention and jumped down and let her horse go. There were about 15 horses working and they thought it was a free-for-all and they started to wig out and girls were jumping off their horses left and right. I was one of the few to stay seated until my horse did a little rear. I went to jump off but my foot got caught in the stirrup so I got dragged a few feet and then managed to unhook myself. As I fell completely, my horse's hoof hit my calf and I could barely walk for the rest of the day and had a huge bruise for over a week. Not fun at all.
