Everything is too dangerous. Nothing is too dangerous. It all depends on the hands of the person doing the training, right? I can wear spurs the size of the Indian Ocean and it's not dangerous because I know where my heels are. Can't say that of some other folks I know.
Tricks are like magic acts. A good magician can make the most insane things look easy, but me? I'd drown in a bowl of cheerios given the opportunity. Tricks with horses are the same thing. Wish I knew how to make my horse rear up like Silver, then I could pretend I was the Lone Ranger. Or, Rangerette as the case may be.
