Once. And it was this year. After about 13 years of riding, not being bucked off...of course I have fallen off plenty of times, but that is different. So it was my fault, not warming a horse up. But I had ridden him every day for about 2 months without him pulling anything. I got on, started him walking and he just blew up and started bucking harder than I have ever seen a horse outside a rodeo arena. I went over his head and landed on my shoulder. Ouch. Safe to say I now lunge my horses up before I get on. No matter who it is. Next day I was so nervous to get on a horse. I decided to get on my old horse. Jumped up bareback, he bucked, luckily I have a better time hanging on bareback than with a saddle. I used to think I was invincible. Not anymore.
