If you have not been to this place, it is worth go there at least once.
You can choose to drive as much as you want and stop as often as you want (
to walk around) http://www.nps.gov/shen/planyourvisit/driving-skyline-drive.htm
Best park for older parents that don't want to walk a lot and it is only 1
hour away from fairfax by car.
