A tarp includes a frame and a cover. The frame includes a grid comprised of at least three repositionable semi-rigid members extending in a first direction and at least three repositionable semi-rigid members extending in a second direction. At least one of the members extending in the second direction overlaps at least one of the members extending in the first direction. The cover, produced from a flexible sheet material, extends across the frame.
