Last night I went on the Nashville Ghost Tour.  Actually, the company has two or three tours.  We took the haunted Tavern Tour.  It was very informative and lots of fun.  I'd recommend it.  I think we'll go back and do the regular walking ghost tour.  We didn't get any good pictures of any 'evidence' but hey...it was fun and informative.  I'd like to go back to some of the places and see if I could get permission for a real after-hours investigation.
