Funny, I've met very few in VA that have a southern accent, including those that have lived here all of their lives. Interestingly enough it seems there is a sort of "Virginia Accent" Virginians never really had the Scarlet O'Hara type southern accent. What you're referring to is more likely the Virginia Tidewater accent. West of the Blue Ridge, where I'm from, you get more of a "mountain" dialect.
Kindly see my post #30 and tell me if you agree.
