Sierra Club doc on Appalachian land and folks, 3 pt story

We hear Sierra Club has done a 3 part tv special on the people and land of Appalachia. They've included a region far bigger than the southern Appalachia area of TN, NC and GA. I sure hope they haven't discounted or left out we Black Appalachian folk. Check info on the series here:
