This video was spurned on by the death of Candice Berner of Slippery Rock Alaska on the Northern Peninsula - who was killed, eaten and partially buried by wolves. The first two clips are slightly gruff, Tom has done his research though and his books offered in the second clip. The third clip is on tracking wolves and identifying them from the signs. Key: 4" x 5" prints! Larger than most any dog and all coyotes.
