We drove along Skyline Drive through Shenandoah Nat'l Park a couple of years ago, and it's a beautiful drive. It would probably be a very challenging ride. Has anyone done it, or part of it? Can you recommend any good starting points? Is there a way to ride it without paying the national park entrance fee?

While I'm on the subject, has anyone ridden Colonial Parkway between Jamestown and Yorktown? That looks like another good ride.
