I ran across this while researching the Go Pro Hero2 video cameras, to use on my bow. These guys used several different ones to film their video. Research aside, it was great watching these guys have a blast on this ultimate slip and slide that they built. At the 3:35 mark the slo-mo is awesome. I am 54, but I promise you, I would have wore myself out on that thing. I probably could not have walked the next day---but it would have been worth it! Ha ha! Enjoy...
