Zach and I rode a short section of the Northern Central Railroad Trail in 2007.  We started at the trail head in Ashland, Virginia (easily accessible via Light Rail).  We rode up to Railroad, PA and stayed at the Jackson House Bed and Breakfast.  Information about the trail can be found at Maryland’s Department of Natural Resources website or at Bike Washington’s website.
