Part of geocaching is to take something from the hide and to leave something in return. Many people set a Travel Bug to be able to follow where an item goes from hide to hide around the world. Think the new world version of that old “message in a bottle” trick you see in movies.
I like to take a photo of a Travel Bug to post online for the owner to be able to see the places it has visited as well as track it on a map.
Here’s a travel bug that is called “Spidy”.
Here’s an Moo-Cow Travel Bug at the ocean in Monterey, California
Here’s the map you see to track where your travel bug has been – there are log entries for each of the places it has been from the people that find it
