My gelding took a skidding fall last summer, he was racing around the paddock going too fast to make the turn and skidded a good 50 feet, poor guy, he left a long mark on the ground and everything. He was fine though, a little embarrassed but he got back up and luckily didnt hurt himself. He also took a similar fall when I first got him about 9 years ago but I was riding. He got going to fast and the footing was slippery, luckily he didnt fall on me!
