What is next for Nik Wallenda?

Possibly walking across the Grand Canyon on a tightrope.

While at a lunch honouring his Friday night walk across Niagara Falls Wallenda revealed that he has permits to walk across the Grand Canyon.

He says it's something he will begin working on very soon.

The one thing he does not want to repeat is wearing a harness.

Wallenda says while it depends on the situation, he would prefer to not wear the safety feature.

ABC insisted he wear a harness or else they were going to refuse to broadcast the walk.

The Niagara Parks Commission unveiled two plaques yesterday honouring Wallenda's accomplishment and stunting history in Niagara Falls.
