I'm sure this has been suggested at one point or another, but I think it would be nifty (and neater) if there were a waste bin of some sort at the swimming hole. So many people forage, braid grass, etc. there that clean up can be a pain if there isn't a composter or beseecher around.
Maybe a hole in the tree like the one in El Bain's or something.
Course, making it into a picnic type area like El Bain's would be nifty too.
