Hunting. Said very well. My husband would appreciate this. Very rarely does he enjoy hunting for the end result of a kill, and actually will not kill unless it meets strict requirements set by him. It's all about enjoying the quiet. The peace. The outdoors. Respecting nature.
Camping bingo game for the kids. Lots of other great ideas on this site. I would have the boys work in teams and use a digital camera to document their finds to follow the principles of Leave No Trace. mh
