Well Morgan C. could help you out a lot with that.
There was a Hornell Raceway in Hornell, NY. In someone's back yard actually

but the track is completely gone, no remnants of it at all. Although I may have a few photos. But I cant seem to locate them as of now.
Seemed like there was a track in every town or City LOL! There was one in Tuscarora called Addison Hills Speedway which raced back in the 70's, also a track in Mills, PA called Mills Speedway. My grandpa, Darrell Dennis used to race at Mills, Addison Hills, and Hornell.
