Zippy was inspired by my business travel from Massachusetts to California over the past 10 years. Every few months I'd fly over the USA and spend a few days in conference rooms only to get back on a plane and fly back over the US.
Simply put, a Travel Bug is a trackable tag that you place in a geocache. The bug becomes a hitchhiker that is carried from cache to cache (or person to person) and you can follow its progress online. - Geocaching.com travel bug FAQ
On a trip to San Jose in March 2012, I dropped Zippy off at a local geocache with a mission, clearly stated on his web page, to visit all the states I've only seen from the sky. I was hoping he'd meet some nice people and get some cool picutes of all the stuff I've missed along the way. This map from Zippy's Travel Bug web page shows his progress so far.
Having sent a slug on a cross country trip I assumed his travels would be slow going, but I was a bit surprised to see him fly across the Atlantic before he made it to even one other US state. So much for his mission.
Even though it hasn't worked out the way I'd planned, it's pretty cool seeing Zippy travel the world. I wonder where he'll head next.
