The second season of the hit Travel Channel series, "Ghost Nation," premieres on April 22. Jason Hawes, Steve Gonsalves and Dave Tango, the paranormal investigators responsible for igniting the ghost hunting phenomenon, are back for more adventures to the other side. This season's locations have bigger mysteries, are more chilling, and have never been investigated on television. Not only will the team be helping distraught homeowners, they're also bringing their skills to an abandoned prison complex and a menacing tattoo parlor.
