History, Mystery, and Tunnels.
Reading The Cosgrove Report sent this guy on a hunt for a missing tunnel possibly used by John Wilkes Booth. After finding the tunnel, and running tours in the tunnel for 30+ years the city all the sudden revoked his business license and a part of history goes back undercover.
Only 9 mins, and really interesting.
