When setting up your tent, it's important to put a barrier in between the ground and the bottom of your tent to protect it from gathering moisture. A good-quality plastic or vinyl tarp should accompany any tent. Fold the tarp into the relative shape of the tent, but slightly smaller. You don't want any part of the tarp to hang out beyond the edge of the tent, otherwise it'll collect water underneath in case it rains. Fold up longer edges and tuck them under the tent.
