Organizers are expecting about 4,000 people to turn out when the Wampatuck Lodge of Masons holds its annual flea market and craft fair next Saturday and Sunday from 8 a.m. to 4 p.m. Nearly 100 vendors will be selling their used and hand-made goods at the rain-or-shine event, to be held on the grounds of the Tri-Town Masonic Building at 38 Franklin St. (Route 27) in East Bridgewater, just over the Hanson border. Food, drinks, and raffle tickets will be sold. The Wampatuck Lodge of Masons includes members from throughout the region, many from Hanson. The flea market and fair is the major source of funding for the lodge’s charitable efforts, which include sponsoring local scholarships, and supporting food pantries and the Toys for Tots program. Admission is free to the event. For more information, call Chris Galvin, manager of the flea market and craft fair, at 508-272-2422.
