There's a movie tavern in town. Also Austin then Texas has the Alamo draft house (now expanding out of state.)
Drive in would be best, much easier to be a smuggler. Don't need a lady with an unreasonably large purse.
There's supposedly an X rated drive in a couple hours from me. That would be hilarious to see.
From taking Bettie's to drive-ins back in the day I remember all drive-ins being somewhat X rated.
