Harper's Ferry sits at the confluence of the Potomac and Shenandoah Rivers, which eventually flow down from the Appalachians to D.C. and out to the Chesapeake Bay. It was the site of John Brown's failed slave uprising (although he was executed there, his body lies a'mouldering elsewhere) and a series of battles in the Civil War. The town is now a historic park (flooded with school kids most days) and it shows its history. For example, right beneath our house stands a ruined church and the headstones in the cemetery behind the house date to the mid-1700s. The Appalachian Trail ran just yards from the house to take you to either Georgia or Maine, depending.
Anyway, it was a fun and relaxing weekend - here's a slideshow of some pics (picasa link):
