Editing Geocaching (section)

====Letterbox hybrid====
This is a combination of a geocache and a [[Letterboxing (hobby)|letterbox]] in the same container. Letterboxes involve a rubber stamp and logbook that are not supposed to be traded and taken instead of tradable items, but letterbox hybrids may or may not include trade items. Letterboxers carry their own stamp with them, to stamp the letterbox's logbook and inversely stamp their personal logbook with the letterbox stamp. The letterbox hybrid cache contains the important materials for this.<ref name="geo_types"/><ref name="Cache Parameters"/> Typically, letterbox hybrid caches are not found at the given coordinates which only act as a starting location. Instead, a series of clues are given as to where to find the cache such as "take a left past the bridge" or "about 25 paces past the big oak tree".
