What to put in your geo cache?

• Logbook and writing utensil At the very minimum, your cache should contain a logbook and a pen or pencil so other cachers can write about their discovery. (Pencils work better in cold climates because the ink in most pens will freeze); mechanical pencils are the best because they don’t need sharpening. The logbook is usually a spiral notebook with the name of the cache written on the cover. Some cache hiders paste their personal logo or some other graphic to the notebook cover. As the cache founder, you should write some profound thoughts about the cache on the first page.
• Identifying information The cache should have some information that identifies it as a geocache, describes what geocaching is, and provides instructions to the finder. (Non-geocachers often stumble upon a cache.) The Geocaching.com site has an information sheet in a number of different languages that you can print out and place in your cache; laminating this sheet is a good idea. Be sure to mention the cache’s name and its coordinates.
• Treasures Add some treasures to your cache. These should be unique and interesting items. Because geocaching is a family sport, initially put a mix of things in it that appeal to both adults and children. You don’t need to fill the container up like a stocking at Christmas. Many caches start out with 6–12 small items. If you want, you can add a hitchhiker or a Travel Bug.

Even though your storage container may be waterproof, always put your logbook and cache goodies into resealable plastic storage bags. This prevents your cache from turning into a soggy mush when someone inevitably forgets to seal the container’s lid.
