IMO making the Forest Service out to be the villain in all this is wrong-headed and counter productive to back country travelers when better planning, obtaining the necessary permit and being up front with the FS are simple enough to alleviate any conflict. Why slink around and attempt to avoid the very people who's job it is to respond to an emergency that may save your life?
The FS has their hands full trying to keep the forest standing and not burning to the ground, protecting and providing access to public land and attempting to curb abuse and despoiling it. In my experience, agencies like the Forest Service are not my enemy, the people who want to get their hands on public land for private gain, the extraction industries, the real estate developers, the bureaus of commerce and greedheads that want to cash it in are.
