Hitch hiker

Hitch hikers are items in caches which are tracked over time. The first hitch hikers were objects with a logbook attached to them. Cachers would write their name in the logbook and put the item in another cache.

There are three types of hitch hikers:

• The original hitch hikers which are simply objects with logbooks and sometimes email addresses
• geocaching.com: Trackables (either Travel bugs or Geocoins)
• Geocaching Australia: Swaggies

The term Trackable is Groundspeak's version of hitch hiker.
