CA RxR 4.10: Route 12: Into the Sierras

[cahwyguy]

Episode 4.10 concludes our exploration of Route 12 with an exploration of the final section of the route: From Route 99 in Lodi to Route 49 near San Andreas. This is a segment that travels through the foothills of the Sierras, running through Lodi, Lockeford, Clements, Valley Springs, and San Andreas along what was originally LRN 24. We also review LRN 12, which we visited before in our episodes on Route 8, for LRN 12 became I-8 between San Diego and El Centro. In our next episode, our attention turns to Route 13, and includes a discussion of LRN 13, the original Sign Route 13 which was quickly renumbered as Sign Route 17, and today's Route 13 which runs through Oakland and Berkeley, although the route is unconstructed between the Oakland Airport and I-880.
