Northern Virginia. I remember when I was a kid and you felt you were in the South when you hit NoVa but now it is all Yankees, I am one, so now it is the southern end of the Northeast corridor.
Further south on 95 there are signs welcoming you to Virginia at rest areas. Obviously, the areas north of them are not “real” Virginia.
I’ve only been here eight years but there are definitely two different Virginias - the “urbane” establishments in Charlottesville, Tidewater, Richmond, and Northern Virginia, and then the rest of it.
