Lyon Air Museum:
Airplanes, Cars, and Motorcycles!

We’ve enjoyed the Lyon Air Museum several times. It's located adjacent to the Orange County Airport on the far side of the runway.

From its website:
Lyon Air Museum has on exhibit some of the rarest operational aircraft and vehicles in the world. Docent led tours take visitors for a walk through history as they stroll among the machines and artifacts that helped define the 20th century.

Exibits include airplanes, automobiles, military motorcycles, and military vehicles.
