Tent
A tent is a movable, lightweight shelter which uses fabric to protect people from wind, rain and from the cold. The fabric walls of a tent are supported by wood or metal poles and thin ropes (called "guy lines"), and the tent or the ropes are usually attached to the ground with plastic or metal pointed stakes, or lattice frames and internal posts in the cases of yurts and marquees. Tent camping exploded in popularity in the 1960s. Manufacturers introduced poles made of fiberglass or aluminum alloys, allowing for a greater range of shapes and a lighter weight tent to transport. Zippered tent doors replaced the traditional flap opening.
