Camp Tecumseh in Brookston, IN. I was the Equine Manager there this summer and it was absolutely incredible. Instead of arts and crafts or bracelet making, they choose from clinics such as driving, braiding and banding, drill team, horse judging, trail, vaulting, jumping, bareback, and many many others! I didn't meet one camper who didn't have the time of their lives! And all the barn hands are quality horsemen ready to help your child excel. It really is an amazing place. I wish I could have had the opportunity as a child instead of waiting til my adult years to train these lucky children's horses :)
Oh, and I know you mentioned that you were quite a ways away, this summer we had campers from ALL 50 states!! And most all of them were return campers!!
