Birddog,
You're right. Those guys are damn particular/peculiar, stubborn even, about where they go. No idea what their market criteria is. They are all over Amarillo, but nowhere to be found in Lubbock or Midland. They are everywhere in the metroplex area, Beaumont, and east Texas, but non-existant in San Antonio, Central Texas, and barely in Austin. Flat out goofy about where they have a presence. And, last I heard, they were not accepting new franchise applications.
