Nik Wallenda walks over Niagara Falls on a tightrope as seen from Niagara Falls, Ontario, on Friday, June 15, 2012. Wallenda has finished his attempt to become the first person to walk on a tightrope 1,800 feet across the mist-fogged brink of roaring Niagara Falls. The seventh-generation member of the famed Flying Wallendas had long dreamed of pulling off the stunt, never before attempted. (AP Photo/The Canadian Press, Frank Gunn) less
