When I heard that daredevil Nik Wallenda will attempt to be the first person to cross over the Grand Canyon on a tightrope, I thought "That's crazy." Not because it's 1,500 feet up and a quarter-mile across with no harness or net, but because the National Park Service allowed it.
Here's the thing, though: it didn't.
Rather, Wallenda's death-defying deed will take place today east of the park, across the gorge of Little Colorado River Navajo Tribal Park. It's on land of the Navajo Nation, near Cameron, Arizona.
