Agriculture is alive and well

Each time I travel I am always amazed at the amount of agriculture land we cultivate in the United States. And I am appreciating it even more now that I am driving through it rather than flying over it. Here is a snippet of my travels this week on my way to my first farm visit. Can you identify the crops?
