It’s not so much the farmers as it is truckers. CA has a lot of agriculture but some places like NYC have a very limited food supply. For some reason a lot of people have no idea how dependent they are on rural areas. I never forgot this tweet from some politician from out East who was flying back from Denver or somewhere and posted a picture of the ground below the airplane (farm fields with patterns from circular irrigation systems) and he says “No idea why the ground looks like that!”
