They have their own farm stand where you can purchase produce and flowers.
The Australians on our trip were going nuts over the prices of fruits here. I think in Australia the fruits are mostly tropical and stone fruits (apricots, nectarines, plums) cost an arm and a leg. They were so cheap here that they were just buying them up at every opportunity.
Fruit in California was really amazing- their strawberries were the best I've ever had.
