For people who have problem finding the superchargers, please plan ahead of time, look at recharge.com for example, or on this forum, people who have been there described where the superchargers are so you don't have to drive in circles! There are photos of the superchargers at all locations, and directions which are helpful.
Gilroy, next to Sony store, http://www.recargo.com/sites/3170, the pin is not in the exact location, but the SC's are at the end of that building is the Sony Store, go down and around the building from where the pin is when looking at the satellite map.
Harris Ranch, at the Shell Gas station on the east side of Hwy 5, http://www.recargo.com/sites/634 the pin on the map is in the correct location
Tejon Ranch, next to Yogurtland (this one is the photo they showed in the announcement)
http://www.recargo.com/sites/7503 the pin on the map is in the correct location
Hawthorne, near Tesla Design Center, look for the rocket!
http://www.recargo.com/sites/7483 the pin on the map is NOT the correct location, you turn from Crenshaw onto Jack Northrop and turn north on the first driveway, you should see a Tesla sign on the driveway, you will feel like you are driving in some backlot, but the rocket is pretty easy to spot once you go down that driveway. I think the satellite map is out of date, so I can't spot the exact location on it.
Barstow, next to Chili's http://www.recargo.com/sites/7557, look at the map, it is showing the correct location
Have not been to Folsom yet.
