Mayor Katjana Ballantyne, along with Somerville’s Department of Public Works and Parks and Recreation Office, invited all local ghosts and ghouls to “Truck O’Treat” on Thursday, October 26, on the City Hall concourse. Costumes were encouraged at the family-friendly event, which included safe Trick-or-Treating, a spooktacular visit from a decorated City of Somerville truck, refreshments and more. ~ Photos by Claudia Ferro
