Danvers is holding its annual open house from 4 to 7 p.m. on Thursday, Oct. 12. The free event, which also features activities to celebrate National Fire Prevention Week and Public Power Week, will be held outside Town Hall and at four other municipal sites. “Open House is an opportunity for residents to get a behind-the-scenes look at what goes on in their municipal offices,” town manager Steve Bartha said in a statement. Among other activities, participants can witness a “Jaws of Life” demonstration and enjoy free pizza at the fire station; check out a utility test truck and ride in a bucket truck at the Electric Division; visit barnyard animals and decorate pumpkins at Endicott Park; and create Halloween crafts at the library. Transportation among the various sites will be provided by the Salem Trolley at no cost to residents, who are asked to park their cars at municipal lots across from Town Hall or at Endicott Park.John Laidler can be reaches at firstname.lastname@example.org.
