Will be driving from Charlotte, NC and want to know if it's possible to go drive south and begin our drive of the Outer Banks from the south end so we can work our way up and go on to VA, MD and DC rather than begin at the north end of the Outer Banks and have to back track. I think there are ferries we can put our car on to cross the water. Is this doable? Would this be very costly? Would this take more time than if we began at the top and back tracked to get to VA, MD and DC? Thanks for any suggestions.
