I did OHSET (oregon high school equestrian teams) for three years. Oregon got the idea off of Wisconsin who I think were the first one to actually start up high school teams (not the high school rodeo, that is pretty different from the high school teams that are becoming more popular today).
It was really fun but I don't know how simular the Wisconsin's teams are to the Oregon teams. But hey good luck! It was a very special expierence for me, and I will never want to trade those memories for anything else. It definitely was a high light of my high school years. I recommend anyone to become apart of a team like those in high school.
