Check in with the government subsidized ethanol plants located within the corn belt. But be prepared to pay. If you are willing to pay the same price for the corn as they can get from selling government subsidized ethanol I'm sure you can buy all you want.
Nebraska...they have a ton of corn there. They even named their univeristy mascot after it.
