Nik Wallenda walks blindfolded between Chicago skyscrapers and it's surreal

US daredevil Nik Wallenda broke two world records Sunday when he crossed the Chicago skyline on a tightrope suspended between three skyscrapers, without a safety harness. In the first half of the stunt Wallenda, 35, walked more than two city blocks and crossed the Chicago River with a tightrope set at an incline of 19 degrees, between the Marina City west tower and the Leo Burnett Building. Upon descending from the tightrope, Wallenda returned to Marina City west via the ground to complete his second and more dangerous feat: a tightrope walk to the east tower at more than 500 feet, blindfolded.
