Yeah, I kinda forgot to tell you about this part in the first book, but there's actually THREE places you have to find in this game. Two of them hide the halves of the copper map.
I'm sure all you experienced hunters and racers out there see a chance to block the other players too. Since once you break the code, you can locate all three spots. So if one hunter or team had half of the map, and another one had the other half....
But I don't wanna hear about any bushwacking kinda stuff goin' on out there either, or I'll hafta' come after you myself, pilgrim. Though I suppose posting up in the final location and bartering for a share might work, if someone got to the map before you. Hmmm.
