Cool Reliable Horse

I have a dear friend from high school, one of the few with which I keep in contact. She sent a picture of herself on a horse she got to ride at times when they spent their summers in Colorado. She and I bemoaned the fact that it is hard to find horses like this anymore, cool, reliable horses. This is what she said about the horse:

This was Stormy, a horse we used to borrow for a week or two at a time when I was a kid in Silverton. He was parade trained, so he would rear back when you signaled him. I was ten when this was taken in Silverton - I would ride him downtown to meet the train and have him walk on his hind legs alongside the train, and all the tourists would take pics!! I was actually quite shy, but not when I got on a horse!!
