Perhaps the saving grace for the nation is the limited mobility, by circumstance or choice, of the more rural parts of the country. And their propensity for wanting to stay away from people, creating natural social distancing.
I’m not real pleased with my county - bordering anger at times recently. But, if rural Montana or West Virginia counties only get to like 35-40%, the virus tearing through those areas will be devastating locally but won’t reach too far beyond a couple county radius.
Of course that changes if a tourist goes in to hike New River Gorge or stops for some Indian Frybread on the way to Glacier and picks up the virus while it’s ripping small town, USA apart. By the summer travel season, people who are willing and able to travel are also likely to be those vaccinated, so even those travel cases being brought home should be minimal. Let’s see what happens post-Sturgis. A lot of those bikers who can take that kind of time off and attend are over 50, political leanings aside. So even that may not be as catastrophic as it was last year.
