The Cache is not at the Posted Coordinates
During our 2015 Summer Roadtrip through 14 states we came across a series of Sudoku Puzzle Caches and decided to bring the concept to Northwest Arkansas.
To find the final coordinates you need to solve the Sudoku puzzle.  Fill in the squares and replace the letters with the corresponding number.  Once you find the final coordinates, finding the cache should be very easy.
