What is Geocaching? Here is the entry from Wikipedia "Geocaching is an outdoor sporting activity in which the participants use a Global Positioning System (GPS) receiver or other navigational techniques to hide and seek containers, called "geocaches" or "caches", anywhere in the world. A typical cache is a small waterproof container containing a logbook where the geocacher enters the date they found it and signs it with their established code name. Larger containers such as plastic storage containers (tupperware or similar) or ammo boxes can also contain items for trading, usually toys or trinkets of little value. Geocaching is often described as a "game of high-tech hide and seek," sharing many aspects with benchmarking, trigpointing, orienteering, treasure-hunting, letterboxing, and waymarking."
There is also a cute short video explaining it at http://www.geocaching.com/. We used the iphone app to geocache with for the first time. There is a free and a 9.99 version. I paid for the app so I cannot speak for the free version. We used the compass function and the map function. When we got down to the site the topographical map and the satellite map were very helpful!
I knew that this cache had treasure to trade, so we brought Jibbitz for Crocs to leave and the boys each picked out two treasures. I highly recommend caching with kids, they loved the hunt and did not complain about the walk at all and we went almost 2 miles there and 2 miles back!
