Boston Globe 5/23/12: Mass. will open 40 miles of MWRA trails to public . ‘No trespassing’ signs along a historic ribbon of land from Clinton to Boston will be removed over coming months, after state officials announced Tuesday they would make a network of trails over a century-old system of aqueducts accessible to hikers, bikers, or anyone seeking a stroll in the woods. The 40 miles of land, long used surreptitiously by residents, will become accessible as the communities are granted permission to share the land with the Massachusetts Water Resources Authority.
