Rrrrr, sounds like a scallywagon, buckeneer old time. Bust out the rum!

Makes no sense, of course not.

Anyways, that sounds like a sweet idea, but instead of GPS stuff, we should just have a map, that points to a destination. At each destination you will find your next clue, or set of clues, on where to go for the next. Bury a real treasure box with smoking goodies, and whoo-hoo! Sounds like a party.

That's what I would do. Not everyone has a GPS, well, not me anyways.
