There's a municipal airport less than an hour drive from me that has a pinball machine from 1975. I'll have to check that out next time I drive through there.
One of my favorite aspects of pinball is finding and playing those odd machines tucked away here and there, thanks to some enthusiast at a local business, or because it’s always been there. Fond memories of an old laundromat in CNY that had a machine of similar vintage..and an equally old coke vending machine.
