Interesting Delaware County Trivia

• If someone wanted to visit every county in a state, Delaware would probably be the easiest. There are only 3 counties in Delaware, the fewest of any state, and they are all neatly aligned, north – south. A short drive down U.S. Route 13 will take care of this in no time.
• Most of the New Castle County Delaware’s border with Pennsylvania is in the shape of an exact arc. This is quite remarkable. Generally borders either follow natural geographic features such as rivers or ridgelines, or they follow straight lines that have been surveyed. The border cuts through lots of people’s houses and back yards. It makes driving around northern Delaware all that more interesting.
• Part of the Mason-Dixon line runs along Delaware’s western border with Maryland. Symbolically this line marked the traditional separation between north and south in the United States. In this portion though, “north” is actually east and “south” is west.
