I think Doug provided some links above. Here's another one:
Tesla Supercharger network
(Note the first post was edited after the September event. But the thread was started in May 2012.)
Thanks for the link. I guess that I was so focused on getting my Model S after waiting many years that I missed the Supercharger discussion.
Anyway, I do know that I ordered my Model S before there was discussion of a Supercharger and was not aware about Superchargers until the Sept 2014 event after I too delivery. I was very happy that I had the hardware and it was already enabled...
