You probably won't believe this, but I have made it out from the wire wiggle to the entrance in 57 minutes flat.
Yeah, we were hauling ass. We were also both in extremely good shape (we were both runners and framing carpenters) and very used to operating in a full running sweat. Framing in Austin in the summer is a hot business. Yes, we had kneepads, and yes, I had been to the wire wiggle before.
Both of us being 5' 8", we could duck walk really fast through long sections around Sherwood Forest. Pretty good burn in the quads, but if yer haulin ass, it don't last long.
Otherwise, nice story. Next time, take a couple of hand trowels back there and continue my dig at the end, where all the wind is coming from that pile of rock. Miles of cave beyond, to be sure. ;)
I won't speak ill of the NSS... but it's even more of subculture than the community, complete with it's own jargon, heros and rituals.
