I'm not sure I've heard of the way you dismount. I'm more of the "tuck and roll" kinda girl. And I, for one, can actually say that I've used it in a real emergency! Lol
I think I was twelve years old...being stupid out in the pasture. Me and my friend had put a halter on the miniature mule, Emery, and tied the lead rope to make reins. I got on (I was light enough to get on the poor lil' guy back then) and my friend lead me around at first. Then she let go of the "reins" all of a sudden. I tried to direct Emery for a couple seconds, but then he decided he'd had enough and took off. At first I held on for a few seconds, then looked down at the ground. He's not tall at all, so I just rolled off, did a somersault, and came back up on my feet. It was hilarious at the time...okay, well it's still really funny.
