Tonight, Larry Matthews will join us on the program. He has written multiple books about caving / speleology. He is also a professional Geologist. I just read his latest book, "Caves of Knoxville and the Great Smoky Mountains." It was a great read, and I learned so much about caving that I hadn't even thought about prior to picking up the book. We'll talk about the history and adventure that is literally under your feet in the Smoky Mountains. I have one little "caving" story that I will share as well. This will be a fascinating show that you're sure to enjoy.
