I trashed the pictures a couple of years ago when my wife and I were cleaning out old files and pictures. I doubt they would have been much help anyway. There was one picture of a light pole with part of the fixture still hanging on it, a picture of part of the front wall, and a couple of overall shots. Everything was so obscured by weeds and brush it just looked like a field of weeds. If you didn't know what it was the pictures made no sense.
I would be interested to know more about the work going on there. Are there plans to make the place a working race track again? I had a flyer sent to me about some kind of reunion on the weekend of 10-21-17. I forwarded it to a friend in Indiana, he drove to the address on the flyer, a small strip mall, and there was nothing going on!
