I been looking at this thread for a few days and it does deserve an answer - I just don't have a good one, sorry. I'm happy to bump it up for you in case someone else has an idea.
I avoid CA. like the plague. Even though it is less than an hour away I don't go there unless absolutely necessary. Heavy traffic and no place to park. 55 mph for RVs and right lane only. They all want to honk but I'm only obeying THEIR laws?? You can smoke dope but don't light up a cigg. Something very wrong that that thinking. And I don't smoke! Fuel tax is very high there. Sorry, I don't have much good to say about CA.
Hope you find good camping and enjoy your stay there. That's not me you see camping with you though.
