Son of Wholesale Club Mystery Cache

This cache was SWAG in the Wholesale Club cache. I placed it 15 minutes after I found it, but the hiding place was to close to another cache and I am now getting it done correctlly. Also adding a Sudoku puzzle to add to the fun

To solve the Sudoku puzzle (see the attachment) you must have the numbers 1-9 in each 3x3 box, in each 1x9 row, and in each 1x9 column. The red letters are needed for the correct coordinates.

It is not at the posted location, but is not too far away. The Sudoku puzzle will give you the coordinates.
