Campsite sight is a term that refers to the items that can be seen at a campsite. The two most common items are a TENT and a tarp, both of which have four letters. A TENT is a shelter made of fabric or other material supported by poles and ropes, while a tarp is a large sheet of waterproof material used to cover an area or protect items from the elements. Both items are essential for camping and provide protection from the elements.
