Forgive me if this has been mentioned before. I searched for it and didn't find any reference to mystery or unknown caches where the final is an LPC. We do this quite often as it is our view that our mystery or puzzle caches should be rated by their difficulty of finding the solution, not the difficulty in finding the final. We do have exceptions but we have had very positive feedback about our finals being easy to find after a difficult solve. Nothing is worse in our book, of taking weeks or months to solve a puzzle, travel great distances to sign the log, only to not be able to find the cache.
