| A county in which it is illegal to serve (or in some cases, to even posess) alcohol.
Most of these in the United States seem to be in the South. They tend to be predominately Southern Baptist counties that don't wish to have the loose behavior associated with drinking anywhere within their sight.
Me, I would just find it sad. Not that I'm a heavy drinker, but I like a good brewpub pint as much as the next guy. |
