Lowell Folk Festival - the largest free folk festival in the U.S.

This is a wonderful annual 3-day event. Held July 25-27 this year, the downtown roads are closed so that pedestrians can stroll along the canals and through the downtown. A great variety of ethnic foods (http://www.lowellfolkfestival.org/food.html), crafts demonstration, and six music stages offer something for every taste.
