Is the fall color season already over by this time?
Maybe, probably.
There is Gettysburg two hours north with Antemium battle grounds (sp?) closer. Shenandoah NP is two hours west. In the DC area I always over estimate drive times so I'm sure Google maps will claim less time to these spots. Although why not just shoot some of the memorials they are pretty cool even if a gizzion tourists have snapped them prior. Let me know if you have any other questions I'd be glad to help. jeff
