|BlueSpark, I don't think that people should limit themselves and what they post for fear that other people will mimic them. Take a look at all of the other videos on youtube xD|
Tell me what that video shows that is useful? At best it is entertainment. It shows me nothing of her skills as a trainer. I don't want to PLAY with my horse, because I am not a horse! My smallest horse is 4 times my weight. I have watched horses play, and any one of the kicks, strikes and bites they inflict on each other could easily kill or mangle me. No thanks.
Coincidentally, none of the great horse people I have known personally have ever 'played' with their horses. I have great respect for the well trained, responsive, willing partners they create.
