Certain things that go — or, in many cases, went — are in the limelight this weekend at the Owls Head Transportation Museum’s Vintage Motorcycle Meet and Antique Aeroplane Show.

Saturday’s spectators enjoyed displays and demonstrations of vehicles including an 1868 Roper Steam Motorcycle and an 1898 Leon bolle Tri-Car; tours of the museum; and a noon “engine rev & hornblow.”

The show continues today. Weather permitting, there will be demonstrations of early aircraft and you might be able to fit in a free Model T ride, too. Gates open at 9:30 a.m.

The museum is located two miles south of Rockland, on Route 73 in Owls Head.
