I remember being in Kentucky for the first time a couple/few decades ago. We sat down at a restaurant table and ordered cocktails before dinner. The waitress said "I'm sorry, but this is a dry county."
We all said "a what?"
No liquor sales whatsoever. Had to go over the county line (and past the patrol cars) to buy liquor.
Which we did....
(I was going through my "grasshopper" phase at the time. Kahlua and cream. The occasional Brandy Alexander, too. Milkshakes with a kick. Not too surprisingly, I wasn't even 21 yet.)
