Interesting District of Columbia geography trivia
The District of Columbia was originally laid-out as a square with 10 mile sides, for a total of 100 square miles. It is only 61 square miles now. The other 39 square miles were returned to Virginia in 1847, forming what is today Arlington County and much of the City of Alexandria.
An individual can stand in all four quadrants of the District simultaneously by visiting the center of the dome room in the United States Capitol building.
Because of its unique Constitutional status, the District of Columbia does not have voting representation in Congress. As a symbol of protest, Washington DC license plates feature the motto "Taxation without Representation."
Possible Counties if the District of Columbia was a State
Nobody knows for certain what country structure would exist in the District of Columbia if it were to become a state. There are two leading candidates though. First, the area could be divided into its established quadrants in which case their would be 4 counties. Alternately it could be divided into its existing Ward structure in which case their would be eight counties. Those Quadrants / Wards that I've visited are in bold. If I have a photograph or other item associated with a Quadrant / Ward somewhere else on my website, there will also be a link.
