Mary Joyce on Antarctica, Big Foot, Underground Bases, Extraterrestrial Humans

In March 2016, Mary was interviewed by the Travel Channel about the secret underground military base beneath The Great Smoky Mountains National Park.  The interview was to be included in an episode of “Mysteries at the National Parks.” 

Originally, the episode was to be broadcast in the fall of 2016, then it was moved to early 2017.  Now the entire second season of the series has been cancelled.
Obviously, season one must have done well or they wouldn’t have filmed shows for a second season.  Now I’m left wondering if the Travel Channel was “encouraged” to drop the series because there are so many things happening in the National Parks that the government simply doesn’t want the public to know about.
