Yep. I have Coal dust in my veins, but that is because I come from a railroading family. I also have some rust, because one of my relatives was an engineer for a big open pit iron mine, bringing the cars from the bottom of the pit to the top, and later working at the benefaction plant, making taconite pellets. My father is a "geologic formation relocation expert." Here in Wisconsin, we've got a few granite quarries in the central part of the state, and limestone quarries in my area, near Lake Winnebago. Some iron mines in the north, and a company is trying to start a new pit. I think I have some lead mining in me, too.
