 Driving through the back roads of rural California, miles of abundant farmland stretch as far as the eye can see. Two miles outside the town of Exeter in Tulare County, a crew of about 20 farmworkers are harvesting plums on a farm managed by the High Sierra Ag Company. They're covered head to toe, wearing long sleeves, jeans, and bandanas under wide-brim hats. Some workers move from tree to tree, climbing the ladders to pick plums. Others load them into large bins for transport.
