Bugging out to the woods is what one does when conducting Guerrilla Warfare against hostile forces.
I agree. Unless Red-Dawn-the-movie or The-Walking-Dead-the-TV-show becomes true, I can't see running out to the woods to eat grubs and things as being a viable option. It sounds romantic, well, kind of, but that's pretty much a fairy tale. As much as I enjoy the wilderness, all my survival gear is aimed at getting me out of it, not into it.
