This is an emergency cache for you. It's intended as a backup for one of those Fall or Winter days when you went to work early, came home late, didn't have time to cache during lunch, and now you've just GOTTA get your cache for the day. Solve the puzzle early, so you'll be ready, and later in the year, get it when you need it.
Now you have to ask yourself, how lucky do you feel? Here's a cache intended to help with the days of the year calendar, but you also might have a pretty good chance at getting a First To Find with it instead. So do you want to wait and find this cache when you need to fill in a day, or do you want to take a chance and maybe be FTF and not have the cache available to find at a later date? Only you can decide. Choose wisely!
The cache is not at the posted coordinates, but is within 0.9 miles. Do not attempt to go to the posted coordinates unless you are in an appropriate vehicle and properly licensed.
To get the coordinates for the cache, solve the following Sudoku puzzle and copy the numbers from the labeled squares into the coordinates. NOTE: The puzzle, as presented, is not a valid Sudoku puzzle due to having multiple solutions. How do you know when you have the correct solution? When the solution gives final coordinates within a mile of the posted coordinates. Use the hint, if necessary.

NOTE: As you copy the numbers for squares C, K, and P, subtract 7 from each number before using it as a digit in the coordinates.
N AB° CD.EFG, W HIJ° KL.MNP
