MacNeil thinks there is "a" Texas accent?

As late as the 70s, you could tell which county a Texan was from by his accent. Things have become more regionalized, but there are still at least 20 different ones.
The same is true in the rest of the South.

"which county a Texan was from by his accent"

You could also tell where in Texas they were raised by the way that they danced (C&W mind you). Outside of Texas, you were noted as being Texan again by the way you C&W danced. Real Texans don't line dance, that's tourist stuff.
