As you may already have guessed, the listed coordinates do not coincide with the location of any of the actual caches. They mark the location where the sneakysheep first met and began scheming together on a variety of projects, most recently geocaching. The actual coordinates of the first two caches are given below. The first part of your mission is to decipher these coordinates and locate these two caches.
The first cache will provide you with coordinates for the final cache location. These won't be of much use however, until you find the second cache, which contains the key to deciphering those coordinates. Once you have accomplished this you will be ready to seek the final cache location.

This lovely poem will guide you on your journey.
Seek the path to enlightenment, a message to receive. Oh beware the false one on your way, waiting to deceive. Linger there and sit a spell before you choose to leave. In quiet champaign far away, await the thorny trees. There silent Enoch holds the key unlocking mysteries. All you need to find the prize is now possessed by thee. Invoking cryptic knowledge, the solution will be dealed. River banks will guide the way to where it lies concealed. Espy the window in the wood, your objective is revealed.
Please exercise caution when retrieving caches to maintain their secrecy from geomuggle operatives.
Good luck with your search and have fun!
