Nik Wallenda walks over Niagara Falls on a tightrope in Niagara Falls, Ontario, on Friday night. 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. (ASSOCIATED PRESS / The Canadian Press, Frank Gunn)
