Just read through this thread for the first time. Dallas is just like LA? What?
I dated a wonderful gal who was a fundraiser for KU and she covered both LA and Dallas (and most other major cities). She had a different outfit for each. In Dallas she wore a skirt. In LA she wore jeans. She could find her vegetarian food easily in LA, but not in Dallas.
Dallas is vaguely sexist Southern manners and teased blonde hair on girls; LA is self-important, egocentric behavior and flat blonde hair on girls. LA has an ocean, surfing and the entertainment industry. Dallas has football fans, BBQ and oil.
Both have lots of fake boobs, lots of highways, and no bookstores. But I don't think the similarities outweigh the differences...
