I have been lurking awhile, but this thread really caught my eye.
There is one in NE Ohio, was called Meander Dragway. You can point Google maps to 41.059874, -80.831180 and see its present state. You can zoom in and still see rubber on the track.
My cousin raced here when I was a kid. One cool thing is it was an airport as well. Occasionally they would stop the racing to let a plane land.
We also came close to losing Quaker City in Salem OH, but they are still running.
