Starting line shack seen in Joe's photo was a late 60's/early 70's addition. After the track closed in 1979, a bunch of us made an alcohol-fueled late night clandestine visit to the facility. Not much left to be 'appropriated' by then, but I managed to get the door to the starting line shack and a return road speed limit sign. Left those with friends back in IL when we moved to AZ in 2007.

I had my first 1969 Chevelle out at Oswego Raceway one summer in 1978 (I think). I believe remains of the strip are still there just overgrown with weeds.
