Help is available to them if they give up. The only thing they are really in danger of losing is their pride.
I used to have a buddy who was interested in those kinds of outtings. We went to the wilds of British Columbia for awhile, and had quite a little adventure. We built a shelter, even a raft to go down river, but the rivers in BC aren't the Mississippi. We also had an inner tube trip down a river in Arizona for a few days. We got there from CA by way of a frieght train, and hitchhiking. We really didn't know where we would end up back then. Good times. Anyway, regarding wilderness survival adventure, I wanted more..., much, much more. But he got a job, married, and now has kids, whereas I am but a young elf who has no hope of "growing up".
I envy their bond, assuming of course.
