OK, so the bats weren't really there. I did see one but, they do live there in the winter....oh where? That would probably be a good thing to tell you. In Crystal Cave in Wisconsin. So after hiking in Northern Wisconsin earlier this summer and learning that some of the rocks and land here are the oldest in the world, I made up my mind to explore more. This place is about an hour from my home and offers a tour that goes 70 feet under the surface to show you a bit about the geological wonders that is the midwest! ;o) Plus, it was 50 degrees underground which was a very nice break from the August heat!
