Maricopa County, Arizona
 

What happens to Maricopa County, Arizona in the official canon?

In 4th edition, five airburst and one surface nukes for a start.

Yep, I saw that. I was wondering if any of that part of Arizona was mentioned in any of the scenarios or earlier sources.

There's a cool train museum in Phoenix on the outskirts apparently that just begs to be in a game

Most of the published modules take place in the Great Lakes region, Kentucky a region west of there, Texas Gulf coast, Nevada and Seattle, WA. I do not have Fall Back or American Outback, but the synopsis of those indicate a location near the KFS and Nevada respectively. So Arizona seem pretty wide open for you to do whatever you want. Just remember that between the five nukes going off in the skies over Phoenix and the surface hit on Luke AFB just west of there, the greater Phoenix area was largely turned into mounds of collapsed buildings and a fair amount of radiation.

Interesting location. I assume you'll be including the University of Arizona's Agriculture Center?

And the adjacent county (Prescott) has the Embry–Riddle Aeronautical University. Get those 2 linked together and you can really start to rebuild

Ahh, I think I found it;

I wrote out a T2K scenario where players take a train out of a slaver's enclave but when no one was interested in playing it I stupidly deleted the folder.

The scenario was, from my terrible memory, set in Chandler AZ.
