Just noticed - Sam bought two high quality backpacks and some hiking boots for a camping trip in the area (so I would assume they might cover him as far as gaiters and/or snowshoes) when we were in Carbondale, so we can knock that off the list. He also picked up some charcoal, which might help keep a fire burning to heat an indoor area, at least for s little bit, or cook a few meals.
Aside from that, I don't think we have a consensus as to how exposed they want to be should Ohanzee bite it, so I can't provide an accounting of exactly what Ace and I would have purchased. It's Ace's money, mostly, so I'll let him decide whether we want to err on the side of caution or save a few hundred nuyen. Of course, Sam is flush with cash, so he can certainly weigh in if he wants to pitch in.
