I have a large group of boys heading to my house for my son's birthday party. Any thoughts on how to keep them occupied with wilderness or survival skills and still seem PC to some of the sheep like parents? Target shooting is out. I am thinking traps and deadfalls while fun are probably not appropriate either. They are beyond the age of just roasting marshmallows for fun. It is muddy, rainy, about 40 degrees with still some spots of snow on the ground. Last year we played football in the mud. My wife forbid it this year unless she can hose them off before they come inside to eat. I can't leave them alone and I would like to share something useful, but I am at a loss. Any ideas?
