If you happen to be in or around the Ontario, CA area, visit Graber Olive Farm. You learn a bit about the history of the area and about Graber Olives. There's a tiny museum, and I do mean tiny, a gift shop and another separate gift shop that sells the olives and nice gift baskets. The ladies that work there are very sweet and when I asked for a recommendation for a place to have lunch, they even called to make sure that it was open. Old fashioned hospitality! I only give it 3 stars because its small and easy to see in 30 minutes or less. Visit nearby Clairmont while in the area. Beautiful little town with fun shops!
