Not really. The starving hordes will roam out into the suburbs to take things by force.
I used to read doomsday novels. In them, the hordes would come out of the cities and steal from the suburbs. At the time, it made sense.
Then I went into my local urban center. I looked around.
Those people are not walking anywhere, any time soon; At least no distance measured in the 10-15 miles it would take to get to my home.
Those of us in the ‘burbs will have plenty of time to prepare.
