Mysteries at the museum, on the Travel Channel started out discussing the history of items at museums. It was interesting and supposedly factual. Last year they added "Mysteries at the Castle" which had interesting stories/myths about old castles. Ok, now they added "Mysteries at the National Parks", sounds innocent enough, interesting, so what are the shows about? CONSPIRACY THEORIES, GHOSTS and UFOS. Why not? Tonight and Well, no good show will last long.
