Ever wonder what some of the huge hundred-year-old vehicles in the Seal Cove Auto Museum’s collection weigh? On May 19 from 10 to 3 pm find out at this vehicle weighing demonstration, during which the Maine State Police will explain the requirements for commercial vehicle weight limits and weight verifications. They will then demonstrate their equipment with some of the museum’s cars. Guess the weights and win prizes. Rides in antique autos will also be offered, weather permitting. For more information, call 244-9242 or visit www.sealcoveautomuseum.org.
