I made a nice simple Sudoku puzzle, had the cache coordinates all entered, and I had even started decorating it, when I tripped over Sandyhead in the kitchen and the tile I was painting it on broke. Fortunately, it broke right along the lines dividing the puzzle into boxes, so I think you can still solve it. After all, there are only 5040 ways the pieces can be arranged – I know the dark blue box goes in the upper left, and the red box goes in the bottom right. And I'm sure there is only one correct way to do it. Nonetheless, if you are like me, you make mistakes, so use the geo-checker before you head out, just to be sure.

When you have solved the puzzle, just read out the coordinates from the grey boxes. The cache is located at N 42 AB.CDE W 71 FG.HIJ
