PG, I would have loved to play with that horse in my younger days! My riding program would have involved a lot of happy trotting on the trail- it would have kept his brain busy and might have tired him to the point that he would have enjoyed walking quietly for a few minutes. Arena, same thing- lots of trotting in figure 8s and serpentines. But at this point in my life, he needs more than I can devote to him, and there's every chance it would annoy me.
