What is a Travel Bug? A geocaching travel bug has a unique tracking number which allows its movements to be tracked online (www.geocaching.com). Objects attached to the trackable dog tag are called hitchhikers and are often assigned a mission. One of the hitchhikers on our travel bug is a little boy charm which we named Kaelin. His mission will be to visit places rich in history and geology around the world and have photos taken of his travels. We will post updates in the newsletter and on the website. It should be a fun way to see where it travels.
