My man Brent about to do the 100' rappel into the gully next to the "Tuna and Chips" wall at Red Rocks. Here, he is 'on rappel' with a prusik back up (below the device) and he's still tied into to the bolts with a double runner through an auto locking carabiner to his harness. That runner will not be removed until he's double and triple checked the entire system before he descends the rope. A bit of techy stuff there for ya. This guy's a natural, in four months he's gone from complete newbie on this very climb to actually doing his first real trad lead on that same climb yesterday. Yosemite here we come in 2010!
