"Not Available in Your Area"- I don't get to see the trooping of the color(s).

Unlike the custom in "English" riding, we in western America, as Bat Goddess said, always implemented neck reining. My father was a horse trainer and when a horse came to us that had learned only 'straight' reining about the first thing he did was teach it to neck rein. It is an economical movement - using only body weight and one hand - and essential when driving cattle; the horse learns it easily.

It is really something to see a cutting horse in action. My nephew has a small place near Bend, Oregon, where he trains cutting horses. It is a beautiful thing to see, probably as close to dressage as one can get in western riding. At a certain stage he drops the reins to the horse's neck and his main role from then on is to stay in the saddle.
