Thanks for the excellent background information.It was at the unofficial and restricted listing pin that people use to get around Plugshare's policy on not letting public users add Supercharger locations. Once Tesla marks it in their own system as open and the database updates, Plugshare's feed will automatically add the real pin to the Plugshare map. This has the effect of making it so that supercharger sites that are in construction or otherwise aren't yet open don't have normal pins. But in the meantime, you can see the "covert" one here: PlugShare - Find Electric Vehicle Charging Locations Near You
