When one is "leaving modern society to venture into the unforgiving bowels of Mother Nature" it's good to remember two things. 1)Mother Nature is indeed "unforgiving" and 2)when one goes "into the bowels" one is likely to become sh*# and be spued out on a dung heap.
I wish them well, and hope they have some level of preparation and skills, even if however slight.
