South from Quartzsite we come to a wide valley covered with a patchwork quilt of small vegetable fields crosshatched with irrigation channels. They seem to be sized and timed to be ready to harvest just a few at a time. We saw the harvesting lettuce, broccoli and cauliflower. We were not close enough to see who exactly was in the fields but I suspect this work is exactly the work they claim no Americans will do. We bought some asparagus and some tasty strawberries. Good stuff.
