If I might add something to the gas info....
Last year in Kentucky there was an ice storm that knocked out power to several cities. Some of the ham radio operators from our area went to help. Even though some gas stations had generators, they couldn’t pump the gas because the internet was down. Gas was there, power was there, but there was no way to access it until they got their internet connections established again.
Our particular area got power back within a week. Including land line service. Most of our issues were wind damage. For flooded areas, especially if comms equipment is flooded, that would be an issue.
Most retailers now need internet to talk to the mother ship.
As my grandfather used to say ‘I’d rather be lookin’ at it, than lookin’ fer it!’.
