I met Chongo in Yosemite, and one of the people I was with said if we got him drunk, he would take us to a "king" swing he had set up at the base of one of his "projects".
His daytime activity was to try and lure newbies into jugging up this free-hanging rope with gear for the next section.
We all got smashed and went to the ropeswing, and it was huge! The rope hung away from the wall probably 35 feet, and it was at least 100 feet to the anchors. We scrambled up the side of this steep slab in the dark with headlamps, pulled the perlon keeper cord and took turns swinging into the void.
The slab was steep enough that you could only regain footing on the in-swing if your balance was spot on.b You only got 2 tries before you would lose momentum.
We pulled several people that couldn't "stick it" back in by the perlon to much jeering, myself included.
It was wild whooshing a huge swing in the dark, and having this slab rush up all of a sudden.
Chongo was cool, a little crazy and frenetic, but who isn't?
