We went on the Historic Tour which entered through the Natural Cave Opening. Before the tour they warned us of the "Fat Man's Misery" and that we would have to squeeze through some areas in the cave, and stoop in others. One man in the group bailed and another kept looking at everyone's midsections apparently to determine if they would make it!! We saw many of the classic cave sites.
Mammoth Cave was out of Junior Ranger books. They didn’t send them when I wrote requesting them along with maps and camping info, so the kids didn’t get MC badges.
We decided we didn’t want to spend another night which we had planned, so after lunch we drove toward Great Smoky Mountain National Park and spent the night at Adventure Bound RV park outside of Gatlinburg.
