When I was showing, my horse got to be very ring savvy. She knew the pattern, walk, trot, canter, reverse, walk, trot, canter, lineup, backup. Pretty much the same in every equatation or pleasure rail class.
I knew she became too ring savvy when one day we were trotting along the rail and the announcer came on and said, "Hotdogs are ready at the concession stand", and my horse broke into a nice canter (she thought the announcer said, "Canter your horses please, all canter". LOL!
