One day I'm going to hide my own treasure and just tell everyone the coordinates, no purchases necessary, no books, no clues, just the exact location somewhere in a remote place, buried under the dirt with a big red X marking the spot - now that's a treasure hunt, it'll be just like that movie Rat Race. How much value would the treasure have to be in order for people to go out looking? Like at least $10,000 I would bet. I'll work some overtime and gather the treasure for it. Call it the UnderMiner hoard.
