If you are interested in what the District of Columbia has for a nickname here you go.

It appears that it has three: The Capital of the World or District of Crime. The District’s Mammal is the Big Brown Bat and American Beauty Rose is the flower.

Interestingly 12 States have Milk as their State Drink. Not surprisingly Florida has Orange Juice. Kool Aid is Nebraska’s soft drink. Tomato Juice is chosen by Ohio and California’s Signature drink is Wine.
