If I remember, one of the few times someone on the show did have a "southern accent", it was during the Leviathan storyline. It was Elzabeth Eis's character Nelle Gunston. She was supposed to be from Virginia. The accent was a little strong for most areas of our state, but I've heard worse. (Elizabeth is one of my favorite and underrated short term players.) There is a lot of variation in southern accents. From working on the phones in customer service, I can pretty much tell what state someone is calling from, even regionally. Atlanta has a pretty specific accent for example. Virginia accents overall aren't as strong as say the deeper southern states, say South Carolina or Alabama, although I admit our former governor and current Richmond mayor Doug Wilder has a pretty solid accent. Kind of like on some Brit shows when they want an American accent, they seem to default to Texas drawls. If you listen closely, you can occasionally hear David or Louis slip into their regional accents for a line here and there. The one and pretty much only time I noticed traces of Lara's Tennessee accent was in the movie "Hi, Mom".
