It's actually very interesting. Anecdotally, as somebody who grew up in a "Foundry" area...when I think of moving to another city, other Foundry cities come up first in my mind as places I want to live. I never really attributed it to regionalism but I suppose it makes a kind of sense. Even regions geographically close to mine don't have the same kind of draw as those close to mine.

nice! From now on, I will be a Mexamerican.

Nice, thanks for this. :)
