... Or someone's gonna get hurt, real bad. It seems people have always been fascinated and captivated by Niagara Falls. Approximately 12 million visitors flock to the Falls each year just to visit. Other folks have taken it a step further and gone over in a barrel, yet others have used the falls as a means to an end (I'm talkin' about suicide). But tomorrow night Nik Wallenda will be the first to, if everything goes as planned, walk above the falls on a tight rope. And he's doing it live on network television.

Just thinking about being in the middle of the tight rope, looking down and having all that space around me freaks me out.

Three hours of television will be devoted to the stunt. Coverage begins on ABC at 7 p.m. with “Countdown to Niagara: The Greatest Megastunts of All Time.” Then the two-hour death-defying show will air live from 8 p.m. to 10 p.m. Be sure to make time to watch it live or DVR it.
