Glad y'all have an interest.

If all members updated their about me location, I would attempt an analysis. Barring that,

perhaps the major clues would be just check out each city's forum traffic and how recent it might be.

Historically, after the Texas areas, Oklahoma has been popular over the years, and maybe Kansas City, Pittsburgh, Arkansas, and a couple others.

You might also check for other local/national review boards -- and, see the scraper sites, too.

Stay safe out there!
