Nik Wallenda High Wire Walk Over Pittsburgh

Nik Wallenda pauses to rest during his walk on a high wire that's over 1000 feet long and 200 above the Allegheny River and Roberto Clemente Bridge without his shoes as part of the Three Rivers Regatta in Pittsburgh on July 3, 2009. Wallenda is the seventh generation of the legendary Great Wallendas, who have performed in circus acts since the 1800s. (UPI Photo/Archie Carpenter)
