I took a fairly short 13-mile bike ride this afternoon on the new, southern part of the Bruce Freeman Rail Trail, over the not-quite-finished Route 2 overpass and on to the West Concord train station, where the trail ended. From there I rode west on Laws Brook Road to the Acton line before heading back and then north to NARA Park, where I looped around before heading back to my car. Stretches of the path were technically closed, but we all ignored the signs and barriers and had a great time.
