I've seen some big wave surfing before but big wave skiing?

Chuck Patterson for those of you who don't know is an animal when it comes to extreme sports. He competes at the pro level in five different sports: stand up paddling, tow-in surfing, kite surfing, skiing and snowboarding. I would have to say this is on the craziest things I've seen though from one human being. Crazy enough that it also looks very fun.
