I would like to ask people who have complained, PLEASE give the specifics where anything written by myself or others is false or incorrect.
The wilderness act directly and specifically makes illegal what you want to do. If the USFS moves forward with what you want, it will be sued silly.
There has been a remarkable change in federal managers. Where in the past, there was a "wink, wink, nod, nod" approach to violating the Wilderness Act when convenient, that is no longer the case, and there are zealous defenders of that Act, both in the gov't and outside.
So, before anything else, one would have to ask the question "is a permanent structure CURRENTLY legally build-able in wilderness". Federal managers have gotten legal opinions, and they are told "no". Cite your legal opinions if you think different.
