Rural GA and NC have already blocked off the roads and banned summer residents and weekenders and hotels and bnbs.
Not sure where you got that from but it isn’t so in practice, at least not where I am. We did a recon yesterday. A local town that claimed it would shut it’s roads had closed nothing, and everyone was walking around in the sun. I think they are trying to discourage the hordes of folks we get from the NY, NJ and DC area here every summer. Half the population here in coastal NC is from NY. They’ve done a lot of good things for our communities. A bit quarrelsome though.
