Daredevil completes tighrope walk over Grand Canyon

Aerialist Nik Wallenda completed a tightrope walk that took him a quarter mile over the Little Colorado River Gorge in northeastern Arizona on Sunday. Wallenda, 34, performed the stunt on a 2-inch-thick steel cable, 1,500 feet above the river on the Navajo Nation near the Grand Canyon. He took just more than 22 minutes, pausing and crouching twice as winds whipped around him and the rope swayed. The event was televised live on the Discovery Channel.
Wallenda didn't wear a harness and stepped slowly and steady throughout, murmuring prayers to Jesus almost constantly along the way. He jogged and hopped the last few steps.
Do you think Mr. Wallenda is brave ... or crazy?
