Ok, so maybe Iowa isn't as exotic as Madagascar or Nepal.   But it's still travel, albeit of a different kind.   Travel into the heart of Red America.   Travel into the land of farms, vast cornfields, tornadoes, guns, soda pop, bibles, super-Walmarts, hunters, smiles, and pickup trucks.   Travel to places where seasonal allergies depend on the corn crop, where vending machines dispense live bait, and where the most exciting event of the year features a swine competition.
