On a somewhat related note, I just learned the following trivia about Arlington County's stance on secession during the the Civil War:
On May 23, 1861, Virginia held a referendum to vote on secession from the Union. Although Arlington’s small, rural population of approximately 1,400 voted, by a 2-1 margin, to remain a part of the Union, it was the only precinct to do so. Most of the state, including the City of Alexandria, voted overwhelmingly in favor of secession.
