A strong desire to travel to places all around the world.
Nia's travel-bug started when she was 18. She has traveled around many countries in a year.
Travel Bug
I unique serial number attached to some sort of trinket used in Geocaching. It is transfered from cache to cache by users and recorded on www.geocaching.com so that it can be traced around the world.
Wow, this Travel Bug came all the way from Hawaii!
