Hi Klara,
Thanks for the ideas. I think you're right about the nut butters; I believe certain oils are high in calories too. It'd be nice to be able to see the nutritional breakdown of this stuff online though. I suspect I'll be spending some quality time at the local health food store taking notes
Foods that can survive without refrigeration would be ideal too. I imagine a number of pickled foods could last for weeks if kept reasonably cool and out of direct sunlight.
As for why I'm taking this trip? Well, I think you already answered that for me -- it should be an amazing adventure!

I'm also at a transitory stage in my life and what better way to figure things out than to be immersed in nature: no traffic, news, cell phones, etc. Just the bare necessities... food, water, and shelter.
Thanks,
Damon
