Per Tesla’s Find Us Tab there is a new Supercharger (in development) location at the Golden Acorn Casino at 1800 Golden Acorn Way, Campo, CA 91906. Given that it is listed as In Development, which is identical to other locations listed as Planned, I am writing that it should be added. It is labeled as the Campo, CA Supercharger
