The large cities would be destroyed first like they are now then occupied by gangs. Rural areas would have groups to protect their crops, food and resourced.
Rural areas need to organize. They have one great advantage, locally elected sheriffs, the right Sherriff would work to organize the militia. And when the shtf he can deputize them augmenting his force. If these militias work with the other town and county militias to form larger groups and a network and framework to mobilize into larger units. Survival is in towns that organize not little hidey holes that you hope to stash your family to live through the ‘troubles’. Big Cities are only a week away from total disaster. That is when a breakdown in the supply chain results in starvation. Cities are havens for Democrats, socialists and communists and should be barricaded and isolated from the rest of the country.
I find it somewhat coincidental that today on Fox Business they have had several plugs about interest in tiny homes during the "pandemic."
Hey, you gotta put your bug out bag down somewhere, sometime.
