There is this cacher who I know, billedm, that creates puzzle cache after puzzle cache. Most are way beyond my capabilities to solve, but some, I can manage. His puzzles are quite challenging, and always fun, bringing cachers to many nice, unique locations. This one isn't as tough as his are, because, well, then I probably wouldn't be able to solve it, but it will give some a nice little cranial workout. I do love a good sudoku puzzle! To find the final coordinates, solve the sudoku puzzle, then fill in the missing numbers based on the basic grid. Good luck and have fun!
The cache is located at
N 27° F-1, G-8. E-3, I-5, E-8 and W 080° C-4, B-9. A-3, H-4, D-3
