Dutch Cop, let me say welcome to our website and forum. Although I cannot be of much help in your search for storage I think that this post would be better suited in the Golden State Region. I will put a copy there for you and hopefully someone in the Sacramento area can be of better help. Good luck and visit with us here often.
