Yes. Our home in Fair Oaks (east of Sacramento) was in what had been part olive orchard, part plum orchard. The trees produced fine olives for pressing and wonderful huge plums.
Wow, that sounds lovely. I don't think I've talked to you before about CA! I went to UCD and I remember the agricultural (corn? lettuce?) fields all around. My sister just bought a house in Fairfield - I guess that whole area has grown so much, I probably wouldn't even recognize it.
