Geocaching (finding hidden items using handheld Global Positioning Systems) and letterboxing (similar to geocaching, but the hidden object is a stamp which the finder uses to stamp a piece of paper proving he/she found the site) are popular recreation activities. There are websites on the Internet devoted to these activities that list the coordinates where items are buried.
