The country watched as Bay area daredevil Nik Wallenda crossed the Grand Canyon on a tightrope.

His next feat could be in the Windy City.

Wallenda told the Chicago Sun-Times that he is scouting possible locations there for a walk this fall.

Chicago is home to the Willis Tower which was formerly known as the Sears Tower and was the nation's tallest building.

While Wallenda said he is looking at the tower, he said it would be problematic because no other buildings nearby are tall enough to cross to.

He has also walked across the Niagara Falls.

Wallenda is part of a family of acrobats that has been thrilling audiences for decades as The Flying Wallendas.
