When I was in the States, I hunted Pheasant every fall on the refuge. It is miles from anything but ranches. They may not have even had to occupy the building, just bring in a few travel trailers and camp next to it. It is or was on one of the few little hills in the sage brush. There is a viewing tower on the hill as well. If the government had any sense, which it no longer does. They would just ignore them. There is not a thing they will upset, except maybe a few Pheasant and coyotes..
Better to occupy the miscreant courthouse.
