Ben, in your enviroment, I'd pack what you do. One thing I have to keep in mind is that other people don't always have the cold weather issues I do.

At least once a winter here, it goes well below zero and sits there for a week. In the summer, it rains almost as much as it does in Seattle, and it can drop from 80 to 40 in the course of a night if it rains at sunset. Add in some wind. In either case, you really should get something warm in you to regulate. I'm more worried about hypothermia than I am dehydration, becuase you have to go at most a mile before you run into water than is purifiable. Also, my plan-B is to bug on foot 80 miles to the family land.

Different locations, different issues. And I'm going to look for those sesame snaps, those sound interesting.
