Occurred on August 5, 2017 / Grand Canyon, Arizona, USA
Info from Licensor: "While on vacation in Arizona, my wife and I visited the Grand Canyon. We drove the South Rim for a few hours, pulling over occasionally for lookouts and views. We noticed a man had walked way out onto a corridor jutting from the canyon's edge. He was standing right by the sheer drop. Then, out of nowhere and dicing with death, he just started sprinting around. At one point he must have been inches from falling. My wife is quite scared of heights and can be heard grimacing in the background. Not what we were expecting to see!"
