Little Lilou Petrucci of the South End gets creative with the Hula Hoop at the outset of the opening day of the SoWa Market on Saturday, April 29, on Harrison Avenue. It was the first time the Market has been open for its expanded Saturday hours, and crowds packed into the district for a beautiful day of shopping, eating and enjoying the nice weather. The Market will be open on Saturdays and Sundays, 10 a.m. to 4 p.m. through October.
