I live in Austin right now. I have lived here most of my life, minus some time in Boston and Moscow (yes, Russia).
But back to Austin... I have had a slight sunburn on my shoulders since early March. I already have a full Bikini tan. I work full time indoors, so this is all from weekends.
As for culture... well, if your version of culture is pro sports and professional movie industry with disneyland, move to LA. If your version of culture is cutting edge film and music, live music, at affordable, non-stuffy, weekly venues, you can't beat Austin. We certainly arn't pretending to be NYC, but we've got a hell of a lot less traffic, crime, pollution etc et compared with LA.
(P.S. For your OTHER point (not the one on race in texas - but, btw, your perspective on that is ALSO skewed), my step-bro, who is gay, moved BACK to Austin from San Francisco. Yes. Because he liked Austin better for that scene. So visit Austin before you start stereotyping it.)
