The above coordinates are fake. To find this cache, you must play the game of Battleship.
Each micro cache in the series represents a spot on the Battleship grid. The lid will indicate a HIT or a MISS. If it's a HIT, clues to final locations of the ships will be given. Once you have sunk (found) all of the ships in the series, you will have the clues to locate this cache. They are under the lids of the ship caches:
Battleship
Destroyer
Submarine
Carrier
Cruiser
Difficulty/Terrain ratings represent the amount of driving and caches you must find in order to get the clues for this cache's location.
There is an unactivated travel marble as a prize for the FTF in this cache.
