So we get it; these are supposed to be difficult.
We're OK with difficult, and frankly, having the GeoChecker site sure can help with the "trial & error" approach, which is much better than the "trail in error" approach.
But some of these puzzles just don't make sense, and we don't even know where to start. Some are just a photo of a Geocacher, or seemingly random list of places. We've searched the photo for hidden numbers, or we've scoured the clues for mathematical symmetry, and just come up stumped, because there doesn't seem to be a place to start.
We've tried to read through the Discussion Forums to get a nudge in the right direction for some of these more obscure puzzles but can't seem to get any traction there either.
I'm guessing we're left with two options - PaF or email the CO.
Any advice out there?
