I emailed Linda, no response yet. I dug through the CA CEC site and couldn't find any new addendums or documents relating to this project since Ver 5, and that was awhile back.
I did find a state park study and it looked good - as in, they were very happy with the usage of Lvl 2 chargers in a select few state parks. I'd love to see that expanded! Including forest service trail heads, though obviously that isn't state controlled. Logistics on that would be difficult though. Actually that's an interesting dilemma - do you add a bunch of tech and 1st world devices (solar, battery, chargers) at forest service parking lots, or do you leave them pristine and more like wilderness? I can understand both sides of that.
