I have a co-worker that started the same day as I did that has been in Clarksville for 20 years. He's been a great source for all things local. He'll be a great source for finding the cool parts of Clarksville.
I had heard about The Nashville radio station WSM recently from a story on Bob Edward's public radio show. It's been around since the 1920's and it is designated as a clear channel radio station which means that its frequency is guarded from interference. Legend has it that most of the country can pick up the signal late at night. I tuned it in while I was driving through Arkansas and I listened to it the rest of the way through Tennessee. It's the only AM station that I have preset on my Bose Wave. Yahoo.
