Sean,
From what I can remember, my grandparents lived in a well established neighborhood which was rather nice. My grandfather owned a vineyard at the time, possibly in Chino, though not sure about that... I remember picking grapes and driving the tractor pulling trailers full of grapes. Have pictures to prove it.
I DO remember Chino and the predominant smell was cows.
Last time I was in California was visiting in Oceanside at a condo that my wife's boss owns...Car Dealer with a number of dealerships. Drove up to Anaheim to take my son and wife to Disneyland since neither had been there ever. We used to go to Disneyland or Knott's Berry Farm everytime when we would visit when I was a child.
My Mom's favorite ride was "It's a Small World..."
Miss her and those times...
