Is it just me or is this a scary sight... beginners inverted rapping...
Aussie style rappelling... It is not that unheard of it, I have even tried it a few times when I was young. I can tell you that it really, really sucks. It is not fun at all. All your weight is put onto your waist which makes you want to pass out. Plus, harnesses are not really designed to be loaded in the back. So is it a death sentence? No, but rappelling the normal way is a lot safer. Anyway, to answer your question, I wouldent be that worried. They will probably quickly realize that not being able to breath sucks.
I had my first encounter with "Sport Rappellers" about 2 months ago. They were all using some variation of a swiss seat tied with 2" webbing and rappeling like this at a local TR crag. The tall point of the cliff is 110 feet. The "guide" among them was wearing what I would takes a fork-lift full body harness, and would make it down that 110 feet in about 5 seconds. He's there trying to teach these 18 year olds to "do it right" by jumping out from the rock in HUGE bounds, throwing the brake end of the rope up & out, basically in free-fall between bounds. No firemans belay.
The climb they were occupying has a bolted anchor, but he didn't trust that, so he had it primarily anchored on a 2' diameter tree 20 or so feet back, backed up on the bolts, and also backed up on the next anchor over (so 4 bolts), Whole anchor built with something that resebled old "gold line"
To top it off, he thought we were insane for using cordolette to extend my anchor over the edge. Spoke up to me about it and said he didn't think i should trust just two bolts or use cord so small (8mm)
You sound like a blast to have a beer with. Do you also have an opinion on what exactly a "meme" is?
Hahahaha... good one. Anybody who disputes what, exactly, a meme is should abseil into an active volcano. Don't stop until your handlebar mustache is burning. Crap, I guess that would include my avatar. Goodbye, avatar.
