NIAGARA FALLS, N.Y. - Nik Wallenda has performed his first practice walk on the tightrope he'll use to walk above Niagara Falls next month.

The Buffalo News reports a couple hundred people came out to watch Wallenda as he slowly crossed the two-inch steel cable strung between two cranes in front of the Seneca Niagara Casino. Wallenda stopped after walking about a third of the wire's length because he could feel the cable moving beneath his feet.

He later placed a short weighted pole on the cable prevent movement.

Wallenda is a seventh-generation member of the famous daredevil family the Great Wallendas, also known as the Flying Wallendas. His high-wire walk is set for June 15.

Wallenda would be the first to walk above the falls themselves.
