It is unlikely but possible that a clue may disappear from its hiding spot. If you are certain that your solution to a puzzle is correct, you are certain that you have identified the correct benchmark, and you are certain that you’ve searched in every possible location where the clue might be, please use the contact form on this site to let me know. Please include:
- the puzzle number,
- the designation of the benchmark,
- a specific list of places you searched (include photos if you can), and
- whether or not you’ve found any of the other clues.
If you’ve looked in the right spot and I can verify that it has gone missing, I’ll save you a return visit by sending you the information you need to continue.
