I know the guys who own that map!
I once listened to one guy give directions to another guy. It went like this:
"You go down 308, past Murphy's Bar, and take a left on that shortcut to Foster's Coach House. You take a right after that."
"Before or after Gentleman Johnny's?"
"Before. If you get to Gentleman Johnny's, you've gone too far. You want the road that goes past O'Doul's Roadhouse."
Those guys must have known every bar in the county!
