A jewel for the type of film that it aims to be. "Deliverance" in NorCal. If you've spent much time in Southern Humboldt or Mendocino county you'll appreciate the references a lot more - not a big of a stretch from how things are. Describing it to a friend I was told that it's based on the novel "Boonville" by Robert Mailer Anderson. I recall there being a shot of the book among others somewhere early in the film.
