Small family farm, Iowa

Looking at a small family farm from above and behind, its back yard trailing down to a creek surrounded by corn/soy fields.  Most of the farmland in Iowa is on a three year corn-corn-soy rotation: two years pulling nitrogen out and one re-fixing it to restore the soil.  Harriet, who's very into patterns thanks to Team Umizoomi, will sometimes call out the pattern in the fields as we drive down the road: "Corn, Corn, Soy! Corn, Corn, Soy! Corn, Corn, Soy!"
