I appreciate the fact that much of what I take for granted is partly due to efforts and…read morecontributions of those I do not see. Just as I work in the back ground, the life of miners is one not seen. Lots of working models of steam engines, mining techniques, and equipment. All very cool in my book, and I can see how most of you would find this dry. Take the underground demonstration mine tour, it is free. Some of the equipment is absolutely unbelievable. Unfortunately, the placards are in German, as is the tour.
