I have been looking at the Geocaching website to influence my Secret London brief. It is a treasure hunting game that uses GPS. I think that I can take influence from how Geocaching is promoted, yet keeps its exclusivity and a secret element.
Geocaching is a real-world, outdoor treasure hunting game using GPS-enabled devices. Participants navigate to a specific set of GPS coordinates and then attempt to find the geocache (container) hidden at that location.
