He has a video explaining the dry suit and I'm sure he had to do some trial runs with the pack and all. Summer would be a whole nother story, not like that is how I would burn my 2 weeks, I would have cried like a baby after a couple days on this trip. Sounds like he is camped outside or on the edge of the BWCAW and will stroll into town in the morning.
I couldn't imagine outfitting something like this, maybe he'll do it naked next time.
