Ok, so this is just ridiculous. I don't know why anyone would even try this. Seriously though, who was the FIRST to say: "Hey, I'm going to climb this extremely high and steep, ROCKY cliff with my BARE hands and NO CABLES!"
Either way, I applaud these people that do this. That has to take some hardcore concentration. I also bet that they are some of the calmest and laid back people you will ever meet.
