DS2 would like a party in the woods for his birthday in June. He has suggested a treasure hunt (find bits of map which guests put together and solve a clue on the back), a ' make your own weapon from sticks' competition 
and a Nerf gun tin can shooting game. He's inviting 6 guests. Any other ideas for games? We are thinking it will be 3 hours long - 2 hours for getting there/ games and an hour for food (planning to use the camper van to cook from). Want to avoid general mayhem/running off/getting lost if at all possible, so idea is to keep them occupied CONSTANTLY!
TIA
