Very cool find,I have more sites to hunt then i can ever seem to find the time to break away from work or the little one to get out on.Your post brings up some sites that i have always wanted to get out to but to date have not.It,s the TVA lake system in East Tenn. DOUGLAS, CHEROKEE, NORRIS lAKES and many more that when the water level is down all of the roads, building foundations etc,are exsposed.As you know this was all done in the early 30,s. You know the finds have to be.So the weather,s mild in the winter months and the water levels down for all who travel to this area. Just tap in TVA Lakes it,s all you need.HH
