My point would be that cars at trailheads regardless of where they are from would be needless. Having an in state license plate does not mean they are local? I agree what's in place is clear and reflect common sense. I'm discouraged when Mayors and Governors in towns & states that rely on tourism make blanket policy against people who live close by but out of state. Discouraged that in some cases it's needed also because people are unable to stay out of bars or crowded beaches or off crowded summits. Discouraged that when local Mayors, (GA), make policy to protect their people, the Governor decides to open the beaches so people can travel to them.
This will continue for some time, I just heard today that one of the more popular NJ beach towns is closing their boardwalk until 7/1. I would expect Cape Cod, the Westerly beaches and others to follow suit. Thinking they picked 7/1 as they hope to save their busy season, however, as we see in South Korea and China, going back too soon can mean a new spike in infected people & a set back. This may be the new normal for quite some time. Vacations may be canceled & certainly the happiest place on earth (not for me but it's their slogan) will not be happy for sometime. At least one pundit has brought up the possibility that there will no NFL season either. Is anyone looking forward to a cruise or a plane trip anytime soon?
April's not even a great month for hiking up north any way.
As I said in another thread, people are incapable of social distancing regardless of what the gov tells them they should and shouldn't do. Until there's a vaccine, staying away from others is the new normal if you want to stay healthy. Of course, economic considerations are relevant as well. Many folks have jobs that require a certain amount of contact and we can't keep the economy suppressed indefinitely. Thus, vaccine is the critical path to getting back to normal.
