My clothes and stuff stays in them all summer. I sleep in a canvas tent and there's a building on each site with a smaller "staff room" where the staff on that site keep their stuff. We encourage the campers to pack in the bins too, and they keep them in their tents with them. The staff who sleep in buildings put a lot of their clothes into the drawers and then put their bins into the basements of the buildigns or keep them in the room if they don't have space for everything in the drawers.
