Hey there -- good luck with your endeavor.
I just want to remind you of what you already know. When you arrive at the wilderness, the universe will still be "logically meaningless." Only then you'll be out in the meaningless wilderness of the universe with a bunch of relative strangers. Not that that's a bad thing.
Maybe you are thinking that the meaning of this move will be "Survival"? -- or maybe a test of your manhood or humanhood? Or do you feel that there is some other inherent meaning built into a quest like the one you're planning?
p.s.... You declare that "the universe is logically meaningless with almost 100% certainty, and later in the same post you assert that "humans are after all meant to live in the wilderness." Ooops! Inherent universal meaning! D'oh! You'd better get that sorted out before taking your party in the wilderness -- it's the sort of thing that undermines credibility in a wilderness trek or cult leader! (well, actually, "what humans are meant to do" is meaning that you
make; the good news is that all
meaning is meaning that you make -- so best wishes in making meaning that works well for you.)
Again, best wishes, even though you probably won't read this forum!
