Sounds a lot like scout camp. Look into scouting. There's a lot of bad press about the BSA, but each troop is really very independent, and your local troop may be far more inclusive than you might expect. As a kid we were shooting bows, all kinds of guns, camping, backpacking, roping, fishing, paddling, sailing, firestarting, tomahawk throws, etc... Especially in KS, I have to expect those kinds of parents are around, you just have to find them.
