When a Travel Bug is created it is usually given a goal by its owner for others to try and complete. Goals can range from a specific purpose, like bringing attention to a great cause such as diabetes or simply to travel the world.
When you find a Travel Bug you can take it from the cache and move it to another, helpig it on its journey. Prior to placing it in another cache you log the pickup on Geocaching.com and then when you place it you log it again. This keeps a record of its movement where you, the owner, and others can watch its progress.
Travel Bugs are just another part of the fun in Geocaching!
Keep on cachin’!
