I had an apartment in Indiana. When I gave directions to my house I used to say, "turn right at the traffic light. There's corn on the left, my house is on the right. If you hit the soy you've gone too far."
When I grew up in rural Ohio, my neighbor grew corn, soy, and had a bunch of pasture for haying. He rotated the positions (and thus the amounts) of some crops so it would depend upon the year as to which was in greater quantity.
