Let me try to break it down for you ExciteBike... The driver for those guide's decision making on the DC route is to schlep lemmings up the mountain and get them back to camp early enough so they GTFO before the next set of clients arrive the same day. At least that is the case for anyone they deposit on Camp Muir. That's about it. It isn't about teaching them anything... It's about turnover.
