A Little Help For My Out of Town Readers…What is a Slinger?

Ok.  I’m kind of surprised by this, but I have noticed that I am starting to get a significant contingent of out of town readership.  So, I began wondering, well everybody knows what a dive bar is, but what about slingers?  I remember visiting some friends in the Twin Cities over 4th of July and they had no idea what I was talking about…of course being 600 miles away from St. Louis and I had a craving for one, something awful.
