This is the giant slip and slide launch ramp built at the Ohio Dreams Action Sports Camp in Butler, Ohio. The ramp is usually used to practice ski jumping into the pool below but now they've added slip n' slides for people with less Olympic ambition. It looks like fun. Fun, and a great way to hurt yourself. And how much fun can a person really have if there isn't a risk of injury? You ever played Monopoly before? Not crazy fun, right? But have you ever played Monopoly on fire? You'll be smiling for weeks! Or recovering. Go directly to jail, do not pass go, do add more lighter fluid.
Continue for the video, I especially liked the guy at 1:20 who does a barrel roll.
Thanks to foxy, who agrees there should have been way more pool noodles in that video.
