Depending on how much you need there's some remnants in my back yard from an old pile? Pieces range from 1"-1.5" Dia.. I will be coming to J-County to my mom's for Christmas sometime? Or can send by mail. Approximately a couple handfulls? Free located in N. Durham. I used them last Xmas...
Progress Energy in Moncure is a coal plant where its brought in by the train cars. I think I've seen some on the side of the tracks coming in and out of that place as it falls off.
And, its not too far from Clayton
I have some left over from Windrock and Harlan that I picked up for "fun" and am now using it as a stocking stuffers for several people
Go to any of the tracks that go into a steam plant. There's one over by Sherrills Ford or down by Mt Holly. Like said above, there will be coal laying all over the place. Park beside the road, you won't have to walk far.
