From Evan Decker of Mentryville, Inc:
If you’ve recently driven along the 5 Freeway (Interstate 5) near the Lyons Avenue/Pico Canyon Road exit recently, you’ll notice some new California Historical Landmark wayfinding signs for the historic oil boomtown of Mentryville which was established in 1876. It is so important that historic sites such as Mentryville deserve the proper recognition they deserve. A huge Thank You to the California State Office of Historic Preservation as well as CalTrans for making these signs a reality.
