You are looking for a green bison tube. It is NOT at the posted coordinates, the cache is located at the final waypoint provided.
In order for you to claim a find you must first have found 100 or more caches in Kalamazoo County, Michigan. This is a challenge cache where you must meet the requirements before claiming a find.
