70's and 80's Southeast MX

I was just wondering if anyone had info or pics of tracks in the southeast in this era. I am especially interested in east tennessee and western north carolina tracks because thats were my dad raced in the 70's. He rode Muddy Creek, there were a couple of tracks in Newport, TN which is were I am from, there was a track in Morristown, TN I think it was called Sugar Hollow, there was a track in the Sevierville/Pigeon Forge, TN area, there was a track around Elizabethton, TN called Hillbilly World I think, and there was a track in Waynesville, NC, and I think there was a track at the 411 dragway in TN that held night races. I have a few pics of these places I will post when I scan them. I am trying to compile info about MX in my area just as my own little project. Any help would be greatly appreciated. Thanks guys.
