Yeah, I read this book keeping in mind that it might all be made up, or the man they call Tom Gorman might be fooling them or exagerating- he had the most outlandish experiences, even after NIDS bought the ranch. But as wild as the claims in this book are, they uncovered other cases where identical things were reported. In the end, the writers admit that they considered hoax, delusions, and other things as explanations and they really don't know what is going on.
In the end though, it makes you rethink some ideas you have of certain paranormal phenomenon-- Are Sasquatch really just undiscovered animals, or something else? Are UFOs behind cattle mutalation, or is the explanation even more bizarre? Do UFOs travel from space, or some kind of portal?
