Query: A Must-See For Friends of the Wolf

This documentary is at once astounding and enjoyable. It provides very real, very true information about wolves. It also portrays wolves in many different ways. The film is fantastic and gripping. It is also mind opening and lovable. This is one of my favorite documentaries ever. I also highly recommend Jim and Jamie Dutcher's other works which include the following: The Sawtooth Pack (book), Wolves At Our Door (book) and a few others. :)
