Geocaching is an outdoor activity in which the participants use a Global Positioning System (GPS) receivers or other navigational techniques to hide and seek containers (called "geocaches" or "caches") anywhere in the world.
David Humphrey, (aka Scotty), is a veteran geocacher from Cranbrook, BC, who, together with his friends, and the Conrad Kain Centennial Society, has created a series of geocaches in easily accessible sites related historically to Conrad Kain in and around Wilmer, Invermere, Radium, Cranbrook, Banff, Canmore, New Zealand, and Austria.
