We've covered the technology used in geocaching and how to select a cache to find at www.geocaching.com.  So.... what can you expect to find inside a cache?

What you find in a cache is directly related to the size of the cache.  A micro cache does not have much room for anything other than a few pieces of paper or a message to the cache finder.  Regular size caches have lots of room for "swag" however.  FYI - swag is a term used to describe the treasures found inside a cache.  The cache details page on www.geocaching.com will often define a theme for the cache and ask those visiting the cache to leave theme related items.

Here is a list of items you may find.

• Logbook - A place for you to write a message to the cache owner.  Usually the logbook is contained inside a plastic bag to protect it from the elements.
• Treasure - Also called swag.  These are small items that may be traded for.
• Special Items - See the next section on Travel Bugs and GeoCoins.
• Messages - Some caches are part of a series and will contain the location or clues to the next location.

Trading

Part of the fun for children is not only finding the hidden location of the cache, but also the opportunity to trade items found inside the cache.  The generally accepted policy here is "even trading" - replace an item you take with an item of similar "coolness" or value.  Don't take a flashlight and leave a McDonald's toy.

You should also write in the logbook the details of anything you trade, what you took and what you left behind in return.
