Literary reference
Jens looked at a map he'd filched from an abandoned gas station. If he was where he thought he was, he'd soon be approaching the grand metropolis of Fiat, by God, Indiana. He managed a smile when he saw that, and declaimed, "And God said, Fiat, Indiana, and there was Indiana." --Harry Turtledove, Worldwar: In the Balance, New York: Random House, Chapter 14, copyright 1994 by Harry Turtledove. The reference is to the unincorporated town of Fiat near the intersection of Indiana State Routes 1 and 18 in Jay County.
