"It is not unusual to find the pullout full on a weekend day"

It sounds like things have changed. I can drive by there when the weather is great and never see anyone there for months on end.

In his 1985 guide, Steiger has it as "the most popular crag in Southern Arizona" as well

I tried to do Jungle Gym last night, and got stuck at the "monkey bar move", maybe it was a result of low light from the sunset but I didn't see the move. I was guessing hooking my leg in the horizontal crack, but it was getting dark... and I had a bunch of other excuses...

Maybe someone out there knows what a monkey bar move is?

I'm guessing a monkey bar move is where you cut the feet loose and use only hands? At least that's what I remember from the playground hehe
