Looks like the battery swap station at Harris Ranch in Coalinga, CA is closed. I heard a rumor that it was closed, inquired about availability, and received the following response:
Presently the Battery Swap Program is not accepting any new requests for appointments.
Because you had to schedule an appointment in advance, the battery swap was not convenient. Since my first and only swap experience, I have used the superchargers at Harris Ranch at probably six more times but never could schedule or plan another swap. I doubt the station will be missed.
