For this POS I'm writing.
What would you think would have been the biggest American city to escape Soviet ICBMs in a US/USSR nuclear war?
What parts of the US in general would you imagine would survive most intact after such a conflict?
With what you know of the US today, would such a conflict have balkanised the US into faction nation-states?
If you had a 24 hr head start on the big one being dropped where would you go and how would you get there?
