I can't stand it when I can figure out the ending before I'm half way through a book or a movie. Here is a challenge for you. You won't in my book. Two army buddies think they are going after a man eating Grizzly. They soon learn their not. The FBi thinks they are going after a serial killer. They find out the hard way it isn't. A lesson learned when it comes after them. There are over 700 911 calls a year in Yellowstone National park. For years this area has been plauged by these strange events. I know you will enjoy this adventure.
