Next time you are out hiking at the Keystone Arch Bridges Trail….on the trail in just after the gate you come to a crossroads. The impressive barn wall is to your right as the KAB trail continues, and to your left a trail continues to the Railroad. This entire area covers the Old Stagecoach Inn and its out buildings. Look for the cellar holes and well. Just before the Railroad stands three stones, each signifying a County in Western Mass. You are standing on the Old Pontoosuc Turnpike. The first highway in Western Mass!
