These tracks are not recently deceased, but deceased much longer: Buckeye Raceway/ Entertainment USA (dust bowl motocross), Gran Prix Raceway in Canal Fulton, Valley View in Malvern, Mathias Raceway (on top of the hill), Mid-Ohio GP track, Wattsburg, PA Friday night MX, Yankee Lake, and many more. My brother and I raced a CRA MX track located on top of a large hill which was quite dusty on Easter back in the mid-1980's. I can't remember the name or where it was located and I am sure it is closed now. Reading these posts bring back some cool memories, but we have some newer tracks today which are pretty sweet too. Make sure you support your tracks!
