I’M NOT AFRAID of heights, but the idea of free climbing the side of a mountain sort of makes my mind explode. Alex Honnold is the expert in free soloing, and while he could probably do this sort of thing with his eyes closed, it’s still a nail-biting experience to watch him undertake such an amazing feat.
