The Sudoku National Championship was just completed in Philly. I'm sure the final puzzle is somewhere on the web, but I can't find it. Has anyone else locted it?

I have a Locked Pair -- that produced eliminations in two houses/units.

Code:
 r8  b9  Locked Pair                     <> 15   r7c8,r8c5,r9c7

I guess the mix of Naked and Hidden Singles caused additional difficulty.
