In the opening credits, filmed on Stone St. in Tucson, AZ, the Pioneer Hotel is briefly visible, and farther down the street, Steinfield's Department Store. The hotel was said to be "100 percent fireproof", a claim that was refuted in December 1970 when fire swept through the upper floors, claiming 29 victims - among whom were Harry and Margaret Steinfield, who lived in its penthouse. The building was repaired and is now a mixed-use apartment and office space.
