I can't say I've never fallen off of other colored horses. lol
Just grays were always my worst.

But one thing I learned is that when you are in a situation like that, you want to do exactly what you normally wouldn't do.

Example...

The horse takes off, and horse now has a mind of it's own. "Weeeeeee, I love running!!"

The horse pretty much forgot that you're riding it, and often pulling the reins won't do much. So you actually have to squeeze your legs to let the horse know you're there, then lean back and pull.

If your have a horse that buck maybe you need the "Barnes No Buck Trainer" LMAO!!!! Not really..

If you're horse bucks, make sure nothing is pinching it, change the saddle, girth or whatever. Sometimes they just want to be brats and the only thing you can really do about that is to keep your head in the game. Think it before your horse does it.

A horse can do anything at any time, however don't anticipate it cause they will do it. You have to anticipate preventing it.
