Two years ago, a polo groom got hung up. His college polo coach had drilled how to kick yourself free. It sure paid off for him.
Not something I've ever learned- is it something you can describe?
My scariest incident was having my horse fall with me riding after hitting an unseen patch of ice under several inches of snow. We were riding a short loop through the woods (solo) on good, fresh snow. While there had been ice earlier in the winter, there had been a lot of freezing and thawing, so the trail had seemed ok given all the new snow. We were actually within 0.5 miles of the barn, so almost home, heading up the last steep hill before we'd circle the turnout fields. Suddenly, in what felt like slow motion, my mare's head and neck went down and it looked like she was folding her front legs under her to lay down. But then, the rest of her started heading to the ground too. I did manage to kick my feet out of the stirrups, just instinct I guess, and she hit the ground relatively gently given what was happening. She sort of leaned to the left and I just stepped off her back to the right. Fortunately, I wasn't stuck under her.
She laid there for a minute, probably as confused as I was about what had happened, but then she started flailing around trying to get back up. Then I realized we had a problem. The ice patch was so large, and the incline so steep, she just couldn't get two feet on solid ground to stand up again. I don't know how long this part went on, but it felt like an eternity. I couldn't think of what to do to help her, and her feet were flying in all directions. I was standing on solid ground off the trail, so finally it occurred to me to just grab her head and drag her towards me, so at least her front feet would have a chance. I don't really remember how it worked, but it worked, because suddenly she was standing again beside me. We were both shaken up, and she was a little stiff into the next day, but I am eternally grateful that neither of us were physically hurt.
That feeling of the horse falling out from under me has stuck with me psychologically though, and even though there was nothing I could have done to prevent it (except not riding there!) it's put a permanent scar on my confidence as whenever things start getting a little hairy on a trail, my instinct is to do whatever it takes not to have the horse fall out from under me. Doesn't make a lot of logical sense, but I guess our fears usually aren't...
