Massachusetts museum tells the hulking history of wars

One of the newest museums in the town of Stow, Massachusetts, housed in a space the size of an airplane hangar, is home to some 50 fully restored tanks and armored vehicles. But the American Heritage Museum has a mission of remembrance not glorification. Special correspondent Jared Bowen, of PBS station GBH in Boston, has this story. It is part of our arts and culture series, CANVAS.
