The problem with telling people to "Go Home" is that we full-timers do not likely have homes to go to. I am currently in southern Florida, and my reservations in state parks have been cancelled for April. I am OK where I am until the 25th and then for four days in another COE park, but after that I have no place to go.
I have two sons--one in the Bay Area of CA, which is too far away, and there is no place to park in his tiny driveway anyway, even if they weren't on lock-down. My other son is in Ohio and lives in a gated community that forbids RVs. I could find a commercial campground there when they open in early May, and I do have some reservations in state parks there, but if those close, I would have to find storage for my RV and move into their spare bedroom--much less safe than my living alone in my motorhome, especially with three kids and two parents potentially spreading germs!!
I have a potential spot in a county park here which is now almost empty, assuming it does not close by March 29. Otherwise, I am going to head north and find a commercial campground or hope Georgia State Parks are open. I am trying to avoid commercial campgrounds because most have small spots that are crowded together--much safer in a state or federal campground where spots are 50' apart than being 10' from my neighbor. And I also have a toilet fresh water valve that is causing my toilet to keep filling, but I do not want to have repair people inside my home right now, so I am making do and keeping water shut off unless I need it.
So, I agree that "Go Home" is not helpful advice when someone asked what was open for RVers.
