FWIW:

I'm not from the U.S.A. but I mostly understand the acronyms and locations. (Heck, I get that list every time I register software or ship something from eBay.) Hadn't heard of the Metroplex. But I would certainly understand DFW.

I know some may have privacy concerns, but be aware that Martin the Mod knows where you are; privacy on the 'net is something of an illusion. (Takes a moment to shudder.)

Anyway, it's certainly useful to know the area being discussed. Doesn't mean we can't all comment; but winter issues (for example) in the coastal areas are rather different from those on the Prairies/Great Plains. And so on.
