On the east side of the train tracks in Hopkinsville, when you're waiting for a train to go by at night, you can see the Whistlestop Donuts sign between the cars as they pass. As the train picks up speed, the bright yellow sign flashes at an increasingly urgent rate: "Whistlestop Donuts! Donuts! Donuts!" This phenomenon is not quite a subliminal message (it's not below the threshold of conscious thought), but it does very effectively lure the mind into sugary, deep-fried fantasies.
