Walk the ground where American thought turned inward
Writers are made by places as much as by people. This is the Concord that did the making. Seven stops over 8.1 miles, about 45 minutes of driving. Every stop narrates itself when you get there, at whatever pace you feel like walking.
It is one of five tours in Concord, each taking a different line through the city. Nothing is booked and nothing expires, so you can start it on a whim and finish it whenever you like.
