I'm wondering if someone can tell me or show in a pic the difference of the Grand canyon, pennycuick, Brookfield, and Canadian style differences. I'm most interested in collecting this CD style ( have about 60) but not sure about all the variations. Any help would be great. Had to post a pic so I'm wondering if anybody has ever used this book in searching for a place to hunt, and if anyone has an extra copy or one they would be willing to sell. Thank you in advance for the help.
