The word geocaching comes from "geo" (earth) and "cache" (hidden storage).
Geocachers log onto a website to find information about the location of a cache usually a waterproof plastic box containing small items such as toys and CDs,
along with a logbook where "finders" can enter comments and learn about the cache's "owner,"
the person who created and hid the cache.
Finders may take any of the items in the cache but are expected to replace them with something of similar value.
They then visit the website again and write a message to the Owner
