I lived in West Virginia and had the opportunity to go into a coal mine there. Wow, them boys earn their money. The tour was done by a retired mine working and he stated the song was pretty accurate about working in mines in the 20th century.Only one thing to say about that!

i'm saddened for the economic downturn in the coaolfields but i am so happy nobody will ever get a horrible phonecall about THEIR miner that won't be coming home healthy or at all.I lived in West Virginia and had the opportunity to go into a coal mine there.

I recommend if anyone can take a tour do it.
