City of Austin is smoke free, but there are a few places that have been grandfathered in: Habana House (inside the cool S. Austin coffee house Ruta Maya); Cool River on the north side of Austin; and Little Woodrows, just outside N Austin in Round Rock. The surrounding cities haven't all gone smoke free yet.
Some of the decks have been cleared for smoking, but this town is so laid back (generally speaking) that when it comes to herfing time, the warring parties generally stay away from one another and pick sides of the deck. The overprotective minivan moms will glare from time to time, but if you glare back they'll gather their gaggle and move away from you :ss
I'm an Austinite and love it here. Lots of growth, lots of youth, lots of fun stuff to do, high quality-of-life here. So move to Phoenix
