Cool! I was out riding in that area yesterday too. Rode from Marshall to Hume to Front Royal and back via Dismal Hollow etc. 63 miles. Didn't see any other bikers though. It was cold, but the sun really helped. I may try to hit Skyline Drive again soon if it's a warmish day. It's kind of a drag having the waysides closed, so there's no place to get warm if you stop for any length of time.
