Gee 'liberty' lighten up. If they were so concerned why did the cabin owners not just buy private land to put up there cabins, no problem. I cannot go out there and just prop up a cabin. This happened at Lake Mead and on Indian reservation at Hawley Lake. You are there subject to the jurisdiction's rules. The Lake Mead people were sites inside the park boundaries. They wanted the cabins but did not want to pay any taxes on the improvements. Essentially they wanted their cake and eat it too. There is no constitutional right to build a cabin on Federal land, built it on private land, where you have protections.
