One of the lesser known attractions is the "Road to Nowhere."  It's a beautiful but short drive with a sad history.  It ends after about six or seven miles, and there is a tunnel you can walk through.  When you go through the tunnel, make sure to take a flashlight.  It's not because you cannot see where you are going.  It is because you want to see where you are walking to avoid the horse poop.  Once you get on the other side of the tunnel, it is quiet and peaceful.  The only sound you might hear would be the sound of a jet flying overhead.
