Wow, great video... even set to Modest Mouse, one of my old favorites that harkens me back to the good ole days!
MAN, I tell ya... before I broke my tibia and knee I had phenomenal balance and was extremely sure-footed. Even considering some of the crazy-ass crap I did back then... I shudder now to think at some of the things (heights) that I jumped, like from rock to rock across a deep crevasse, etc. But EVEN THEN you could not have paid me good money to do what they're doing in those videos! Just think if a big gust of wind came up on you... you'd be mountain lion food in the blink of an eye.
No, thank you!
