Upbeat and athletic guides give everyone an intro and fit you into double-clipped harnesses. They start you out on a baby ride to get the hang of it. You then take seven more-thrillinng rides, interconnected by short walks and footbridges, ramping up (literally) to the final King Kong—whose name speaks for itself. By then everyone will be ready to jump into the blue and watch the scenery whizz by. The lines do make a "zipping" noise, kind of a long hum, which adds to a soundtrack of yeehaws! and birdsong. Some seasoned zippers let it all hang out, like trapeze artists in a freefall, flying backwards with one hand securely on the harness rope.
