Subterrestrials

This week our fearless investigator John Link explores the area of SubTerrestrials. As far back as the Ice Age some believe that our species went underground and formed subterranean cultures that may have survived with us even today.  Hidden and underground in caverns networked under the ice layer...could they still be among us and evolved into creatures like the Sasquatch, Yeti, Bigfoot or C.H.U.D's???  Or are they extinct?  Call in tonight and listen to the debate or give us your own thoughts on the subject.
