Olinda was once as booming oil town in the city of Brea, and was established in the1890s (which is old for us Southern Californians). At the time, the hillside was spotted with pumpjacks, drilling as far as 8,000 feet below the surface. The Olinda Oil Museum is part of a 12-acre preserve.
The car pictured above is a classic, Ford Model T, and is part of the museum. But that's a different subject for another time.
