The cache is not located at the given coordinates. Solve the puzzle below to determine the cache coordinates.
Your mission, should you accept it, is to find something the fifteen people below have in common (not currently shared by the person above).
Special Notes about the 2019 Puzzle Challenge: To be considered for Fastest Solver points, you must verify your solution with Certitude. Finders will receive Top Finder points when submitting Found It logs to the cache page. All "point" scoring is arbitrary, subject to change, at the discretion of the cache owner, and probably completely meaningless (unless you just want to be announced sooner at the celebration party, assuming one happens sometime in 2020). The real challenge is to see whether I will have enough time to create a puzzle each month this year! To maintain fairness, hints should not be offered by the cache owner or other solvers until the fifteenth of the month.
Special Notes about this month's puzzle: Another last-minute special. The "unknowns" are all placed at #3 for this puzzle. It's an ivy hide; so I've given a pretty specific hint in Certitude.
You can validate your puzzle solution with certitude.
