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.
The suburbs in greatest danger are those with mass transit that goes to them.
In the post commuter age the suburbanites may have to resort to extreme measures to make sure they are not a mass transit destination any more....
