The Tulsa Speedway was a dirt track on the property of the Tulsa County Fairgrounds. The track was leased by a promoter (various ones over the years), who was responsible for all facets of the operation including maintenance, security, concessions, the first aid station, and of course, keeping ambulances on hand.
Between when the funeral homes exited the ambulance business in Tulsa in 1970 and Oklahoma's EMS law took effect in 1982, the speedway contractor owned and operated his own ambulance fleet. (Although Central and then EMSA had exclusive contracts with the city during that period, it didn't apply here because county property wasn't technically in the city limits.) Two ambulances were staffed during all activities, and a third car was usually kept in reserve.
Attached are photos of some of these rigs over the years:

Park Row combination was purchased new by the Reed-Culver F.H. in Tahlequah, and then by Morehead's in Comanche in 1969. After being traded in again, she was sold to the speedway in 1974. This car, originally a two-tone light brown and cream color, featured factory front and rear air, red parking light lenses, and a Q1B whistle. She was later sold to an indivdual near Cushing, after which she was exported to Europe.
