There on the truck is what will be eaten in not very long. You might even be the one to eat it. Or it might go to a relief effort in South America, Africa or elsewhere. This farmer has just unloaded a hopper of grain in to his truck. Before he can unload more, someone will have to take that truck in to unload, maybe at his farm or in town at the grain elevator. He probably won’t stop combining though, and will keep adding the nation’s stores of grain.
