Found these today. 2 are near my home. Grandview Bowl is now a soccer pitch, but the kids and I ride bikes around the old paved oval. The city encroached on it and they moved it to... Cassidy Speedway, was a Clay oval I worked at as an announcer for several years untill locals closed it down because of noise (and a lot of BS stories about wrekless driving and booze on the road to it). It was awesome racing. We even had the "old Timers there (20's to 40's bodied and powered, with modern safety cages etc. They were my favorite.
