Climbers flock year-round to iconic destinations that offer good views and good rock that will test their skills and stamina. This particular wall, however, is not for the faint of heart. At 4,000 feet, it’s not as tall as Yosemite, but there’s no other wall in the world with as much gut-wrenching space underneath. You could say that the climbers Max Fanning and Hank Caylor are equally versed in the art of hanging on and letting go. For just $1,000,000, you can try your hand at this suspended wall, but don’t forget your helmet, or for that matter, your parachute!
