I’d say move away from cities, into an area that can feed itself from crops raised inside a 100 mile radius. A lot of America might as well be a moon colony, if it had to feed itself locally. What if the trucks and trains full of food stopped coming, for a number of reasons?

I moved from SoCal to North Florida, and the above was a key reason. We have plentiful water, I even have a shallow (35’) hand pump well in my back yard that produces potable water. Everything grows here, so if we make it past a year with a broken national transportation infrastructure, we’d have a shot at establishing a local infrastructure.
