At 6pm tonight, Chicago will play host to daredevil Nik Wallenda’s next feat: a tightrope walk across the Chicago River. Starting from Marina City’s West Tower, Wallenda will make his way south across the Chicago River to the Leo Burnett Building’s roof, then after making his way back to the West Tower, he will walk another tightrope to the Marina City East Tower completely blindfolded. Weather reports are indicating wind gusts up to 50 miles per hour. Further endangering Wallenda is his decision to not have a safety net hung out below his routes. Just in case you’re unfamiliar with the buildings in question, the Leo Burnett Building on Dearborn and Wacker stands at 671 feet while the Marina City Towers across the Chicago River are roughly 588 feet high.
