FWIW -- hubby and I did the Skyline Drive from Staunton VA to Front Royal VA in about 5 hours. Going north from Staunton, we went as far as the visitor center at Big Meadow stopping at most of the scenic views. Then we realized what time it was, and that we needed to get into northern NJ by a decent hour -- so we only stopped at two or three more scenic viewpoints before Front Royal and getting back on I-81.
