This lets you become an adventurer in your own backyard. There are about 100 to 150 new caches added to the Geocaching site each week and Irish is impressed by the growth in the sport's popularity. But when you look at the small community of geocachers and how it has spread all over the world, it couldn't have happened without something like the Internet, especially as quickly. The attraction in this hi-tech hunt is much more in the finding rather than the treasure. A cache traditionally will have a logbook for people to leave messages, and other items that easily could be described as somewhere between junk and knick-knacks.
Some caches contain disposable cameras so that treasure seekers can record their moment of victory.
The etiquette allows you to keep something from the cache as long as you leave something behind, so that the contents of the cache are a living entity. Irish likes the caches that are in unusual places. In Belize, there is a cache buried on an island in a lake. In Egypt, there is one cache buried within view of the pyramids and another buried on a sunken tug. Someone with a sense of humour has buried a cache outside Bran Castle, legendary lair of Vlad Tepes, otherwise known as Dracula.
