Last I checked, Austin is south of the Mason-Dixie line and has plenty of small towns around it that will be glad to remind you that you’re in the South.
RDU definitely has an enterprise tech scene. So does DFW!
Then don't live in the south. You'll get paid more, the weather will be nicer, and you'll meet less numbskulls with confederate flags painted on the hood of their trucks. Win/win/win.
