That's crazy. I hadn't seen that! Thanks for posting! I can't even IMAGINE the type of balance that guy has. It's crazy! And when he's in a water, it looks like a six-horsepower boat. ;)
It also makes me feel better, because when I run around in the arena and Java is following me, his ears are back -not pinned, but back- and so are all of these horses.
I love when a horse will play with you that way (no I am not a Parrelli follower) and now I'm curious if Java will follow me over a jump without a halter on... hmm...
