World's Longest Sudoku - Finished!

I set a goal to complete The World's Longest Sudoku Puzzle by August 15.  Today, 4 weeks ahead of schedule, I finished the final puzzle!  With our need for instant gratification, it feels good to plan and complete a long-term project.  And I hope that these 8,929 correct answers in the 167 interlocking puzzles will help keep my brain young.
