This is a continuation of the BLT trail started by TheGeneral1004 and annes2. As such, all of the hides can be found on or near the South Dakota/Minnesota or South Dakota/North Dakota border. While all of the hides themselves are park-n-grabs, the difficulty rating reflects the puzzle and the terrain rating reflects the precarious ditches that are filled with tall, tall grass.
