This cache can be
logged independently, but it is also part of the Tulsa Sudoku
Challenge puzzle, which is cache
GC1RKNB. If you want to eventually find the
Tulsa Sudoku Challenge cache, then pay special attention to the
log sheet when you find this cache. Be sure to copy down the
Sudoku "given" digit from the log sheet, and put it in its place
on the Tulsa Sudoku grid. If you haven't already printed out the
Tulsa Sudoku grid, you can find it
here.
After you have found this cache, and signed the log sheet,
please make sure the rubber o-ring seal is still in place, and
screw the cap back on snugly, so that the log sheets won't get
wet.
Once you have discovered all 17 of the Tulsa Sudoku "Given"
caches, and copied down the "given" digits onto the grid, you can
work out the Sudoku puzzle and find the challenge cache. Good
luck!
