When creating and releasing COWBOY I tried to use this book's "out there" format (or lack of) as a benchmark for how what to do and what not to do. I certainly wanted anyone -not just twelevers- who bought into the game to know how to find out if it was still going, no matter what. I actually put this in the book so folks were assured of how to find out. Looking at what other authors/treasure hunt creators have done has been a great tool for the do's and don'ts.
I'd be curious to what your thoughts were if they are completely different than anythign else that has been said about whistle pig. I truly have thought that if you could get the correct general area, that the WP logo or "Shadow" would be the actual outline of something you would see on a map or web based map such as google. To me it could be a body of water somewhere.
In the case of most hunts, only time will tell. With this one, time seems to make it more vague and diluted. With The Secret, you can speculate that the remaining nine have been found, inadvertantly dug up, built over, moved on accident, altered, or anything BUT, the difference is we know the hope is still there... this gives those a mystique that differs quite a bit from Whistle Pig.
Wait, what were we looking for again? Exactly.
