Very impressive. I would love to learn how you trained them to do those things... as well as yourself! I started doing trick training with one of my mares but I haven't kept it up and it was all her, not me.
They look like stunt horses; do you do anything with them? Exhibitions or TV/ film work?
Looks painful to me:)
A lot of time and training went into this, I'm sure, but shouldn't you be wearing a helmet? (of course, I'm one to talk... because I don't wear one either, but if I were doing what you are doing, I think I would :)
