FILE - In this May 16, 2012 photo, Nik Wallenda performs a walk on a tightrope in the rain during training for his walk over Niagara Falls in Niagara Falls, N.Y. For his latest feat, the professional daredevil is going to try to do an unharnessed tightrope walk high above the beach in Atlantic City, N.J. Atlantic City tourism officials are hoping 50,000 or more people show up to watch Thursday, Aug. 9, 2012, as Wallenda attempts to traverse a line connecting the Atlantic Club Casino Hotel to the Tropicana Casino & Resort.
