It's like a really wet open-top bobsled i.e. a lot of fun.

Having been brought over from New Zealand and reassembled on the ski slopes of Mountain Creek in Vernon, New Jersey, the 1,975 feet long inflatable slide is probably the most enjoyable way to get downhill on a hot summer day in the mountains. The entire ride lasts anything from just over a minute to 90 seconds depending on how much you gun it, which is long enough to enjoy but just short enough so you don't get bored. Although if you ask us, some ramps and jumps wouldn't go amiss, especially at the end.
