This Wikidedia entry brings back some fond memories of the late, great Action Park of New Jersey. Where else could a fourteen year old ride a go cart at highway speeds? I didn't know that local doctors referred to it as "Traction Park," but I'm not surprised. When I went with some friends in 1981, one misjudged the Tarazan rope ride and landed on the ground instead of the water, causing a moderate leg injury, several others got nasty scrapes from the Alpine slide, and I felt at great risk of drowning in the wave pool--every time I tried to climb out, a wave would hit me and knock me off the ladder. How this park managed to stay in business for twenty years, I don't know, it was probably the single most obviously dangerous place I've ever been.
