This is a Play Anywhere Wherigo. You will need to start the game in the middle of a small open space roughly the size of a baseball diamond to play the game.
The posted coords are a good place to park to find the cache but not to play the game. Please don't block the gate as you could be towed.
You have been invited to join an expedition to explore a Pyramid found buried in the Oregon countryside. Is this Pyramid built by one of the Mesoamerican civilizations or did one of the African countries like Egypt cross the ocean to start a colony far from home? Or maybe the CO has been watching too many Stargate SG-1 episodes again. Any way you look at it, you're going to have to play the game if you want to find the cache.
You can download the cartridge here.
Smartphone users will want to download the Pocket PC cartridge.
