In the world of geocaching, there is a word that has been adopted from Harry Potter. That word is muggle. In the Harry Potter series the word muggle is used to describe a non-magical person. In the Geocaching world is used to describe a non-geocaching person or someone that doesn't know what a geocache is nor how geocaching works. Those of you that are muggles (in the geocaching sense) may not know that a geocache is a treasure box for a person with a GPS to find. Coordinates are posted on the internet that point directly (within about 10 feet) of where the cache is hidden. When you find the cache, you are to sign the log, trade anything you find in the cache with something of equal or greater value, and then put it back. Muggles, which don't understand what the rules of geocaching, will steal the items inside and possibly move it to a new location rendering it unfindable.
I have personally hidden 4 geocaches to date. I am sad to say that last week I discovered that my 4th geocache has been "muggled". All four of my geocaches have been muggled over the years. I must say, in the Muggle's defense, that this geocache was first hidden 11/12/2005, so it has lasted quite a long time without having problems.
I'm not sure if I'm going to replace the cache or just let it drop off the map of geocaching.com
It is too bad that we live in a society that doesn't respect other people's property.
