That's a really good point, I hadn't thought about having a spot to air the bag out on the second half of the trip, even if the weather's not cooperating.
I had thought about dropping a cache, and for some reason I was thinking 20-mile, which would be kind of out of the way. But at the dam, I can basically just drive right up to the BMT-AT intersection? If the worst happened and it was gone, at least I'd be in a relatively populated area. Shouldn't be too hard to catch a ride from there. A metal paint can, I suppose?
What socks? Just glanced at a couple and only saw a weight on some patagonia's. Almost a pound!?
Yeah, I guess the poncho would be lighter, multi-purpose, and probably cover the pack better too (covering the vulnerable part between me and the pack).
