Confusing New Video Suggests We Must Climb City of Rocks in Jean Shorts (WATCH)

I go through much of my life in a confused state. So, not understanding things is OK with me. But, there's a new video that is pushing my limit of what I'm willing to not understand. It's suggesting (I think) that to climb at the City of Rocks, we must be wearing jean shorts.

I know. This sounds crazy. But, what else could this video mean? Watch it for yourself and see if you understand it.

Here's the explanation from whoever shared this video on Vimeo:

(*blank stare*)

What in the heck? You want me to climb the HUGE rocks in the City of Rocks in jean shorts? Not gonna happen.

In the video, all I see are a couple of disembodied legs flailing. Ironically, flailing is what I would be doing if I tried to climb at City of Rocks, too.

I'm sure there's a point to this video, but danged if I can figure it out. Can you?
