This attraction is trying to be a revolutionary war site, an antebellum/abolision site, a civil war site, and a modern-day tourist trap. You can't park in Lower Town, but the shuttle bus is fine. Jefferson Rock was much smaller than I expected, but it was pretty cool. Tip on finding Jefferson Rock: head up High Street and you'll see stone steps on the left which will take you up to the rock. The hike across the bridge over the Potomac River is a little boring, but at least I can say I've been on the Appalachian Trail.
