Golden State Model Railroad, Richmond
Tucked away in a warehouse in Miller-Knox Regional Shoreline Park, located in Richmond CA, lies this large and impressively historic model railroad layout. It spans three scales of trains and a vast swath of the great state of California. It even includes a miniature Oakland Mole, the transit precursor of the Transbay Tube. Not a long drive, and a lot more to see than what I managed to capture.
