You will have to solve the puzzle to find the actual coordinates
for the cache.
If you have not done SuDoKu puzzles before: You must fill in all
the missing numbers so that every row has 1 through 9, every column
must have 1 through 9, and all 9 blocks have 1 through 9. This is
NOT math - it is logic.
There are some letters in the grid. They will finish the
coordinates as indicated in the puzzle.
N 28° 0A.BC9 W 082° D0.E6F
