WATCH: Nik Wallenda & His Sister Walks Cross A Highwire Over Times Square

If you haven't heard of Nik Wallenda, you should know that he's one of the best and bravest people to ever cross any highwire. He's crossed over everything from roller coasters to Niagara Falls and recently attempted one of his most dangerous feats, walking high above Times Square with his sister Lijana crossing the highwire from the opposite direction. Both of them are seventh-generation members of the Wallenda family circus troupe and you can see their enormous amount of of experience really show through as they pass by each other in the video above. Nik stepped over his sister..on a highwire.. hanging right over the heart of Times Square. Talk about crazy!
