The Wild Bunch - Jan Gangsei

Three unlikely friends--brainiac Hector, bullish Jack, and sarcastic Paul--find themselves braving the wilderness in search of the mythical Beast of Bear Falls in this hilarious MAX novel.
As far as Paul Adams is concerned, the idea of a weekend camping in the nearby state park with his dad's two college friends and their sons, Hector and Jack, sounds like a nightmare. But even he finds the myth of the Beast of Bear Falls--a legendary Bigfoot creature--intriguing.
The trip gets off to a rough start, and calamity and disaster follow catastrophe. Against all odds, arguing most of the way, the crew face all sorts of obstacles natural and man-made. Can the three boys make it to Bear Falls and uncover the truth about the Sasquatch living there?
