I just realised that I have never seen or used it, neither crude oil of course, but there are more variants of it than this natural mineral that powers a lot of the world.
What led to you seeing or touching coal?

Took a tour of an old/historic cooal mine once. There was still a seam in the wall. And they had some coal and stuff in the gift shop.
You might also see it if you see a blacksmith demonstration. (For example, Historic Fort Snelling, for any one near MSP airport looking for something to do.)
