Not only does this show the county line, it shows - albeit subtly - the distinction between the city of Bay Lake (pink tint - home to AKV, BWV, BCV and VWL) and the city of Lake Buena Vista (green tint - home to SSR and OKW). You can also see the RCID boundary (unfortunately, the map is out of date - I believe some of the Northwest RCID lands have been deannexed as part of the Western Beltway project).
