InTown Concord celebrates the 40th Annual Market Days Festival this weekend. A half-mile of Main Street and some side streets are closed to vehicular traffic for this three-day event. Featuring 150 vendors offering a vast array of food and shopping options, the festival turns historic downtown Concord into a pedestrian boulevard. There will be live music in Bicentennial and Eagle Squares, family fun activities on the State House Lawn, a beer tent, bouncy houses, a classic car show, the Concord Arts Market and so much more. Tens of thousands of people will come out for this event, making this central New Hampshire's biggest free community event of the year..
