One hundred years ago, 99 percent of us were farmers growing our own food, while 1 percent lived in the cities. Now those percentages have reversedâ€”and yet we all have to eat. Where does our food come from? Despite shrinking farmland, the decline of the farming family and the rise of big ag, every summer the wheat belt in Americaâ€™s heartland swells with amber waves of grain. Many American farmers still turn to custom harvesters to cut their wheat. Since May 2017 I have been following one such crew, the Wolgemuth Brothers from Lancaster County, Pennsylvania.
