They will be all '80's photos that I'll pickout and scan. It should include the "eastway" & "westway" variations as they were the final designs of the track.
For years I'd go by Ontario Motor Speedway and see that the dirt that supported both turn one and turn three were still there 20 years later (infact, the OMS sign is still being used). Riverside was distroyed for a part of a parking lot to a mall. Then they ran a road diagonally through the middle just to make sure it was dead. In fact I believe the cement plant is still there.
