Yes they did stop Alaskan snowbirds from coming through with their motor homes. The Alaskan governor intervened on their behalf but was denied. Essential travel like military people are still allowed through but they are getting harassed by locals more and more it seems. Kind of funny, there was a story in the paper recently about Canadian snowbirds going to Florida and apparently they are allowed to do so. Some friends of ours from Calgary have a house in AZ and they went south about a month ago and no problems.
