There is a clear distinction amongst southerners from Amarillo to Wilmington and Lexington to Everglades City insofar as dialects and vernacular
Mid south versus Deep South
Appalachian versus Country versus southern accents
I can tell Deep South educated class drawl instantly versus mid south of the same class
Country accent is similar all over here
Texas has a more teeth together country sound except in the park cities or Alamo heights etc
You’re too humble, as I saw you correctly identify exactly where people came from time and again based on their accents and speech patterns alone. Like an X-Man know one knows how to utilize.
