NOTE: One flaw with the Wherigo cartridge is if you are within the first zone when you start the cartridge it will not work. Therefore start the cartridge at the posted coordinates to be safe.
This is a basic introduction to Wherigos, It is a virtual multi with the cache and log at the end, The posted coordinates are only the starting point. As this is mostly virtual you don't have to worry about muggles (maybe at the final). To play you must download the cartridge from Wherigo.com. You can copy and paste the following link to your internet browser to download. http://www.wherigo.com/cartridge/details.aspx?CGUID=a25032be-0410-48aa-ac38-deb4392bd4a2 A smartphone or GPS (like a Colorado, Oregon or Nuvi500) is required to run the cartridge. On a smartphone you must dowload the free Wherigo or WhereYouGo app in order to play the cartridge.
