There may be kind of a fire sale for some old tracks. The guys that want to buy old tracks may find a gold mine.
Possibly the family doesn't care to continue. Since Buzz owned the real estate, it was about the only way to keep a business like that open. No doubt it would be a money-losing business if it tried to be self-supporting. The family may not want the bother of owning the property Buzz owned and may sell the real estate he owned. Generational change is a fact of life in many family owned business. Buzz's kids are not spring chickens.
If NY'ers are lucky, somebody may buy one track and move it to an affordable building and keep racing alive in the area. Not sure you can find afordable property in NY for a business model like a slot track.
We may finally find out just what is in the basement and what other tracks Buzz had. I think it's been said that he has a Sovereign in storage.
