Yes, North Carolina is a very big corn state. Corn importing state that this. Check out this nugget of information from Ron Heiniger over at N.C. State:

?If North Carolina was a country all by itself, we would be one of the top five corn-importing countries in the world? It?s no longer that you grow a little grain here and sell it at a corner market, and it ends up in your neighbor?s feed lot.?
