Geocaching. was created with the sole purpose to promote the new sport of Geocaching. This site was designed and programmed by Jeremy Irish, a web developer and tech guy in the Seattle, Washington area, with the help of Elias Alvord and Bryan Roth.  Geocaching is an entertaining adventure game for gps users. Participating in a cache hunt is a good way to take advantage of the wonderful features and capability of a gps unit. The basic idea is to have individuals and organizations set up caches all over the world and share the locations of these caches on the internet. GPS users can then use the location coordinates to find the caches.
