I don't know how they even got the boats that close. My god...
We hiked up/around to Whitewater Falls in the Asheville area of North Carolina (http://www.romanticasheville.com/ima...aterfalls4.jpg) and there really is little that can top sitting on top of a water fall 10 feet away from the edge. At 411 feet...Whitewater Falls is a baby to this what these guys are on top of!
