IPSWICH — More than 300 Ipswich Middle School students walked 10 miles from the school to Great Neck and back on Friday and raised more than $18,000 for the Ipswich Community Food Pantry. The pantry, which is located at the Southern Heights Ipswich Housing Authority site, is a program of The Open Door, which serves 10 communities on Cape Ann and the North Shore. Friday’s event marked the return of the school’s annual Walk for Hunger for the first time since the onset of the COVID-19 pandemic.
