I remember the old Atomic Speedway in East TN having big car counts back in the 70's and 80's. They'd run a few heat races, a consultation (non qualifiers) feature and a feature. Those were the days!
Sadly those days, along with Atomic Speedway, are gone. I raced on asphalt in middle TN, KY and North AL in the mid 80's and early 90's. We had good car counts back then, but nothing like the old days at Atomic.
