Amen. Not many show or arena horses would have a prayer going many of the places we go. No way, I'd take a show horse to the mountains. Good way to kill you and the horse.
Bought a champion TWH several years back. Trained to do everything, except take care of his legs in rough terrain. Poor guy never did make it as a trail horse I'd take on a trail. Sold him to a flat lander. They get along just fine.
