Cobb County’s Department of Public Safety is hosting a free Halloween festival Saturday, October 24, from 11 a.m. to 2 p.m. at its Emergency Vehicle Operations Course, 1285 Al Bishop Drive in Marietta. Children can trick-or-treat among decorated vehicles, meet rescue and emergency personnel, and climb aboard large trucks.

The event also advertises displays from police, fire, E911, emergency management, transportation and animal services, including specialized K9, dive and tactical units. It is a rare opportunity to see how the equipment works from a few feet away rather than from a road shoulder. Food trucks and a photo booth are listed, with costumes encouraged.

For kids who like vehicles and engineering, this has more to offer than a standard candy walk. Go for the equipment demonstrations, ask how the vehicles are configured for different jobs, and take a few close-up photos of clever mechanical details.

What to do: Visit Cobb’s free truck-or-treat Saturday 11 a.m.–2 p.m. if the boys want to see real emergency vehicles.
