CACHE IS NOT AT POSTED COORDINATES
When we were pretty new to this game we published a puzzle called "The Ramblings of a Madman". We thought we were so clever. But as it happens, that puzzle was absolutely fraught with ambiguity, something I despise in puzzles. I didn't even realize how bad it was until another cacher asked me about it and I tried to solve my own puzzle. Ugh. So anyway, here's a puzzle in the same idea, but now with lots less ambiguity. BYOP.
