I used to think the same thing. And around here, it's actually against the law to drink (non-alcoholic included) and even eat and drive.
I live in a state with "dry" towns (alcohol can't be sold in those towns. It's against the law.), a town called "Two Taverns" that has no establishments of that kind, a town called "Gamble" with no casinos (gambling has finally been made legal), and you need to go through Blue Ball to get to Intercourse.
