The process of burying a
capsule filled with a
logbook and various other items, recording the location with a
GPS receiver and then publishing that location on the web. Other people can then find that location using their own
GPS receivers and make a note of their find in the logbook. They can also take one of the items in the capsule and leave one of their own. Its kinda a new tech adventure game/treasure hunt.
