I made that video with a cheap camera and am sorry that the sound is so bad. I should either remake it or subtitle it! It was just a little goofing around my friend and I did. But the use of ONE REIN is very helpful, and moving the horse over with a whip or the hand works.
Buck didn't use that, and I think I shall work on thatl. Mac is super easy to mount now, but he wasnt' like that at first. It took me about 45 minutes to train him to siddle over and be good. And he looks forward to the little treat I hand to him from the saddle, after I am in it. I know, bad habit.
I do spoil him some.
