A person of American Indian descent in a prior forum in which I participated, stated that she was personally aware of a number of such people living in the mountains in Montana, if I remember correctly (could have been Wyoming, but it was in that area at least). She said many were US military vets that just wanted to be left alone. Public lands – more power to ‘em. This nation let them be broken, then wouldn’t/couldn’t take proper care of them, and just sloughed them off like old scabs. Let them be.
