they kinda messed up the geographic pattern when they opened Splash Mountain, however...it's more or less in the Southeast, but it had to go there b/c it wouldn't fit anywhere else. However you do pass over the Mississippi when you cross from Frontierland to Liberty Square, and time is rolling back. Also...the brown walkway that goes down the middle of the street...people used to dump their..."waste" shall we say, out their window, so there would be a stream running down the middle of the street with it. Also, in Liberty Square, check the angles of the shutters. They are all a little off 90º because in the Revolutionary War period, they would take off one of the leather straps holding the shutters up for...one of their weapons or clothes...I don't remember what exactly, but something they needed for the War...consequently, the shutters hung at a slight angle. Disney overlooks nothing!
