After being introduced to geocaching by one of my friends, I got involved in the game/sport/hobby in December 2005. I continue to be involved and don't foresee anything that could stop me just because of how much I enjoy it.
What is Geocaching?
The easiest way to describe geocaching is to call it a modern day treasure hunt. The "treasure" isn't gold or silver, however, they're usually tradeable items, such as toys, that people can exchange. The "map" is really a geographic coordinate (latitude and longitude) that's input to a Global Position System (GPS) unit.
What kinds of things go in caches?
A Logbook
At the very minimum, all geocaches (commonly just called "caches") must have a log book. This enables a visitor to document that they did, in fact, find the cache. The log book, depending on how big it is, also allows for feedback- which might include comments about how difficult it was, something that happened while finding the cache, how nice of a day it was, etc.
Tradables
Many people also enjoy trading for items. Often, this includes:
Toys
Novelty Items
Books (often book exchanges).
The general rule is that if you take something out of a cache, you should put something of equal or greater value back. In my opinion, it's better to replace wh
at you take with another item, as opposed to money.
