In one of the routes it will give you the option for a town map. I believe it is Normans route. It will happen directly after the talk with Eric the express boy. When that town map shows, click "The Town" and do 2 of those events (Restraunt, Bar, or Billards. Doing all 3 will make you go home.) There is an alley directly behind the bar, click that and theres your scene. Another scene that involves the map is "The River". That will net you a CG with a sweaty and very attractive worker.
