I couldn't tell you how many times I've fallen off a horse. I guess the worst was I had a cheapo arab gelding that I was going to train and possibly resell, or keep if we bonded and he turned out nice. I'd done a ton of ground work with him, and took him on trail rides, leading him, taken him horse camping. So his first real trail ride was the Friday of Memorial Day weekend. He got spooked by rustling leaves, and took off running and bucking down the trail. I wasn't going to fall off, but I couldn't stop him either, so I decided that before we hit a tree (it was very deep woods) I would just bail off. Well, duh, it's like instinct to not let go of the reins, so I was then being dragged backwards, trying to keep my feet, when WHACK I hit a tree with my head, backwards. I let go of the horse and crumpled into a heap at the base of the tree. But then he was scared more and came back to me so I could save him, at a full gallop. I thought he was going to run me over, so I stood up to move behind the tree and CRUNCH my leg was broken...(I never felt it happen, just felt my head hit the tree). I was fortunately wearing a helmet. So everyone then came back, and the horse had run off back to camp, and I got on my daughter's horse to ride back. Then went to some tiny ER in the middle of nowhere, up in northern Minnesota. They x-ray it, it's broken, no duh, the doc says he's going to cast it up to my hip! I'm like, why? It's my fibula, non-weight bearing, can't you just splint it? So he disappears for nearly an hour, and comes back and puts this little air splint on it. And gave me a pair of crutches and a prescription for codeine. I wouldn't take the codeine, since I was sleeping in the gooseneck of a horse trailer and didn't want to feel like puking, in the middle of the night, with a broken leg, and try to deal with that. But I did go riding on my daughter's perfect horse, with my crutches and all. Sold that arab, I never liked him again after that.
Now my daughter has had some very frightening falls. Her first horse was a 20-something retired arab broodmare- the sweetest horse ever. So we're out trail riding, and come to a foot-high log, everyone steps over it, except Jenny who leaps over like she's stadium jumping or something. And as Kelly, who wasn't expecting that, keels off the back, she gets kicked right in the head. Helmet, luckily.
Then one time Kelly and I were riding double, her in front, in a group, on a rails-to-trails trail. I wanted my horse, Annie the Perfect Horse (arab) to walk, not prance. So I was bugging her to tuck her head, slow down, and she reared up. I thought she was going over backwards, and just slid off. But I didn't take my kid with! There was this split second of frozen time- could I reach the reins before Annie realized she was free, and took off to join the group? No! So she starts running, and Kelly starts screeching, and I'm screaming HANG ON!!! and running, and they're approaching a highway, when the others ahead hear the commotion and block the trail and Anne skids to a halt, and Kelly falls off the side. No damage.
But then I'm going to teach her to stop a running horse, so it doesn't happen again. We're in a ring, and she's practicing trotting and stopping Anne. But then Anne takes off with her and Kelly can't follow instructions to stop her (not sure why- just intimidated, I guess) and falls off, whacking into the railing of the arena so hard her shoes fly off! She's got a tiny scrape on one ankle. I'm like, "Never, ever tell grandma this happened!!!" So I drop her off at my mom's house that night, and the first thing out of her mouth is "I'm not supposed to tell you how this happened!"
