The Medford Family Network concludes its summer concert series with a performance by Ben Rudnick and Friends. Stop by for music, sing-a-longs, movement and dance. There also will be free books and community information available. Family activities will take place from 5 to 6 p.m., followed by the concert from 6 to 7 p.m. New this year, concertgoers can pre-order pizza and picnic blankets for delivery at the event. Visit the Friends of the Medford Family Network website to order by 11 a.m. on concert day.
