NIAGARA FALLS, CANADA -- Friday, Nik Wallenda, of the "Flying Wallenda's" family, will attempt to walk over Niagara Falls on a tight rope. But, the stress Wallenda is feeling isn't coming from the stunt.

Wallenda will try to cover 18-hundred feet on the wire 200 feet in the air.

He'll walk on a seven ton cable across Niagara Falls. The wire vibrates in the wind. Somehow Nik Wallenda doesn't seem bothered by any of that.

What he is worried about is paying for the walk..and the cable, which he had to buy. He could end up a million dollars in the hole.

He says he's frustrated by hotels and businesses on both sides of the US Canadian border that want to capitalize on the walk...but won't chip in to pay.

He's also not happy with the tether he's forced to wear by ABC tv -- which is broadcasting the walk.

Family members say they're afraid that'll upset his balance...although it could save his life.
