I'm very familiar with Kingstowne and other portions of F'fax County, though. Some Kingstowne addresses are written as being in Alexandria despite its being in F'fax County - this I know because my day care provider is in Kingstowne and the F'fax Co. Police set up speed traps at the end of her road. I live in SW Fairfax County, work in Alexandria and shop all over the county. I'm pretty familiar with a fair number of points in F'fax. Arlington County? Not so much, apparently. : )
