For daredevil Nik Wallenda, a 460-foot long tightrope stretched 150 feet above a race track is small potatoes compared to his high-wire treks above Niagara Falls and the Grand Canyon.
So for his stunt Saturday above the Charlotte Motor Speedway in North Carolina, Wallenda added a challenge: his sister.
Wallenda was joined by Lijana Wallenda, starting at the opposite end of the wire and meeting in the middle. When they crossed, Lijana crouched down so Nik could carefully step over her.
Nik Wallenda also performed at the NASCAR track in Charlotte last year.
