Remember this epic Skywire walk across the Grand Canyon? Nik Wallenda performed this gut-check of a lifetime LIVE on the Discovery Channel last year and it was insanely awesome! He took one break during this walk that made my heart drop- it was eerily reminiscent of the infamous walk that claimed the life of Nik Wallenda's great-grandfather, Karl Wallenda. But, the accurately named "King of the Wire" completed his walk, and in that moment he became the FIRST person to walk across the Grand Canyon! Amazing! Watch Nik walk without a harness or safety net yet again live tonight on the Discovery Channel as he performs a 3-piece stunt in the Windy City! Amazing indeed! #NikWallenda #TheFlyingWallendas #KingoftheWire #Skywire #WireWalk #GrandCanyon #Wallenda #discoverychannel @discoverychannel @nikwallenda
