The camp is not coed, so boys attend during the odd-numbered weeks and girls attend during the even-numbered weeks While at the camp, participants make crafts, participate in various sports, help care for the camp's resident animals, have cookouts and hayrides, and help assemble toys for local underprivileged children The camp provides all food as well as materials for all craft classes and the toys to be assembled.
