Nik Wallenda -- Walking Tightrope in Chicago Wind Might Blow ... Hard

TMZ TV


Nik Wallenda survived walking a tightrope across the Grand Canyon ... so, it totally makes sense he would try it 650 feet up, between two Chicago skyscrapers! BLINDFOLDED.  Why try this In the Windy city??? Nik says it's just in his blood.

We'll just try to forget that ole great grandad Wallenda's "mistake" is also in his blood. Yikes.
