I can share this first hand experience when a track closes.
As a kid my parents would take us to Freestate Raceway. It was up the road and across the street from Laurel. Later in life it made for a kick-butt double header.
Freestate was sold to a developer and closed after the 1990 racing season. They put a CarMax on the site. Freestate had a life sized horse and driver sitting there when you drove on to the track. The developers kept it and it's sitting next to U.S. 1 near the CarMax today.
This was 25 years ago and to this day when I drive by that site I still get pissed off. I always bark something out like loud like FU$&% Y&$ DeFRA%$#@.
Good luck to all of you and your local tracks.
