i'm not sure about that. PA is one of those states that don't recognize dual residency, or at least makes it very difficult. once my parents received their PA driver's ID, their NY ones become null and void. a non-resident VA license would be good in PA, but i'm not sure a VA resident license would be considered viable for a PA resident, or vice versa.
of course, a VA resident with a FL or UT permit would be fine. again, i'm no lawyer, or even a paralegal. until someone actually posts the statute pertaining to this, and proves me wrong, i'm going to assume i'm correct, because safe is better than sorry.
and to the person who proves me wrong, i owe you a beer the next time you're in my area.
