The wonderfully dangerous sport of WINNEBAGO SURFING was invented by
rock climbers in a national park in Western U.S. The surfer lurks in an
overhanging tree, rock, output port of tunnel, etc., and hops a ride on
the top of a slow-moving motorhome driven by a tourist. He waves at
passing motorists, jumps up and down noisily on the roof, or hangs
upside-down over the windshield and makes faces at the driver (while
anchored securely with climbing equipment, since the mark invariably
hits the brakes)! Ideally, the surfer catches another tree or pre-rigged
rope and disappears vertically before the mark can dismount to
investigate (camouflage clothing is useful here). An informant in the
National Park Service says that the Department of the Interior ordered
the NPS to deal harshly with Winnebago Surfers, and to suppress all
mention of Winnebago Surfing in internal newsletters and publications,
lest the practice become widespread.
