You took VA8 north to get on I-81? What was the pavement like on the north end of it?
If you had turned south it becomes NC8 and goes through Winston-Salem and Lexington. That part of our state is famous for barbeque. VA8 and NC8 is long and we haven't been on all of it. In places it turns into city streets and Interstate highway.
Virginia and North Carolina have some "time machine" roads that give you a look into the past. Glad you enjoyed it.
Most of the pavement was actually in pretty good shape. It was a blast to drive (to the limits of the vehicle - which is pretty good).
Echo the "time machine roads / towns" aspect. If we weren't is such a hurry, we would have stopped and done some exploration. Problem is the wife needs her wheelchair for long distance exploring (which we had with us - primary reason for the wagon). And we're well acquainted with NC BBQ (as well as KC).
