To shorten this up a bit, this dude basically goes skiing with a parachute on, and glides at insane speeds just above the mountain. He also will go over the edge of a cliff and its just crazy to watch!!
So it's hard to tell whether or not this is fake, but if it is indeed a fake then they pulled it off pretty well. The first time i saw this i was like, notsureifsrs.jpg but whatever it is, this video is fun to watch.
