Riverfest is an annual event held along the banks of the Charles River in Waltham. Food trucks and amplified music are always part of the scene—but the focus of interest is on the craftspeople who offer their wares for sale, and the demonstrators who teach or inform us, or inspire us by example. 

Everyone as usual, except the little boy in blue, seemed to be having a good time. It was late when I arrived, so I contented myself with a few portraits of the participants. (See also my related photo-stories, Artist and Machinist.)
