Find yourself some "real" Austinites. Something like 4/5ths of Austin's population is "foreign", and this figure is pretty close to literal. It's a big east-coast city in Texas now. But there are "real" Austinites that are every bit the wonderful stereotype you've heard. They have started moving out of Austin lately though, to cities like Elgin, San Marcos, New Braunsfels, or Fredricksburg. There's still some local flavor south of the river in Austin. But everywhere else are just Los Angeles and East Coast transplants that brought their road rage and shitty attitude along with them.
