Equus Oils
Equus Oils is a gas station located on Interstate 65 owned and operated by Joseph Wheattree. The station's facade features a large horse head, in reference to its name, itself a reference to the 1973 play Equus by Peter Shaffer. The station is in debt to the Consolidated Power Company who has in turn throttled its electricity.

Its design – namely the wedge-shaped canopy – is based on that of the Tramway Gas Station in Palm Springs, California, or the Phillips 66 station in Flagstaff, Arizona, photographed by Edward Ruscha for Twentysix Gasoline Stations.
