Most likely areas where they perform a lot of family separations that can also be close enough to other common locations with many people of color to be a useful training aid. Arizona is close to the south with wide open cities and Chicago is indicative of a lot of northern cities with choose packed buildings. There's already a ton of teaching facilities for individual houses or foreign locations. This is really not that surprising. If they were building something like Minneapolis or Boise I'd take more notice.

Is there something special about Chicago and Arizona?
