The posted coordinates are not the actual coordinates. To find the correct coordinates and this cache, you must first hunt bison on the GTT. Hopefully you have recoded numbers and colors of the six bison. They are numbered #1 to #6. You are looking for a regular cache just off the tram road leading from the Game Lands gate#79 along Beula Rd. The numbers correspond to the appropriate numbers of the caches, replacing the letters that stand for the color of the bison tube on which the number was found.
