I found this video while I was just browsing around on You-tube. More horses just keep comin'; I couldn't believe it. And it must take some major leg muscles to ride standing on two horses! I once watched a video of another guy, Tommy Turvey, on Clinton Anderson's TV show. Tommy had Clinton ride standing on two horses and he was about to die after just two minutes. It was pretty funny.
It is pretty long but don't give up on it! By the end he is controlling an insane number of horses. Pretty cool!
