In the short story "Westward the Course of Empire Takes Its Way" by David Foster Wallace, which appears in his short story collection Girl With Curious Hair, the town of Collision is the site of a fictional McDonald's commercial shot in 1970 and the location of a present-day reunion by ex-McDonald's commercial actors on which the story hinges. Wallace creates a fantastical origin story for the town involving a wealthy Chicago woman driving in a southward direction who accidentally hits, and kills, a farmer in a tractor and decides, in a fit of guilt, to make a home out of her crashed car, thus kickstarting the town of Collision into existence. In an extra bit of satirical irony, the manslaughtered farmer is Ray Kroc, Sr.- father of McDonald's "founder" Ray Kroc.
