Daredevil Nik Wallenda is set to make another walk, this one over the Grand Canyon.

Wallenda was on the Today Show Monday morning to announce June 23rd as the date of his long anticipated wire walk over the Canyon without a harness.

It will be broadcast on the Discovery Channel

Wallenda was openly critical of the clause in his contact with ABC last summer that forced him to wear a harness while wire walking over Niagara Falls.
