Nik Wallenda performs a walk on a tightrope with the Skylon Tower in the background during training in Niagara Falls, N.Y., Tuesday, May 22, 2012. Wallenda can't visit a new place without envisioning a wire strung high above his head: Linking buildings, landmarks, nations. Even as a 6-year-old at Niagara Falls with his parents, he pictured walking a tightrope over the raging, whitewater maw. Now 33, he's ready to live out that childhood fantasy when he attempts Friday, June 15, 2012 to become the first person ever to walk a tightrope directly over the brink of Niagara Falls.
