Niagara Nutcase | Metafilter: "Grew up in the town next to Niagara Falls. My favourite story is the one about the kayaker from TN who thought he could build up enough speed to shoot out of the water's drag at the falls. He thought that he woud make it if he could land the kayak in such a way that the force of impact would be distributed along the reinforced hull. They found his arm."
