After my Geocaching post went live, I got a correction back from my Brother-in-law Jim, who introduced my family to the sport. He wanted to clarify a few things about geocoins and their purpose for my readers. Jim wrote "
The coins do not actually have an emitter. They are placed at a location and the coordinates are provided at geocaching.com. We download the coordinates and find the cache with our GPS. Each location lists what geocoins or travelbugs are contained in the cache."
For the most part, geocoins are not collected within the sport, although Jim said that some people do keep ones they find specially attractive. The main point is that you do not take something out of a geocache without replacing it with another item. At theGeocaching.com site they mention three basic rules:
Take something from the cache
Leave something in the cache
Write about it in the logbook
It's that simple. Visit the Geocaching.com site to find out more!
