I lived in Newport Washington for a while, right on the Idaho border. Spent a lot of time in Idaho. I saw many bumper stickers, "DON'T CALIFORNICATE IDAHO.' I asked an Idaho guy about that, he said they were sick of Californians moving in. He said that an immigrant from California better get those California license plates off of his car in about 48 hours. If an Idaho boy saw California plates, he would get a broken windshield and a few flat tires.
