Well I am going through an old list of trackables that I saved to my iPad/iPhone over the last few years and this trackable was one of several we have seen in either a cache, at an event, on a car, on a person, on a dog. If we can remember the circumstance of the discovery I will note it in the next paragraph. If I have kept the date, I will edit it back to the date seen.
Saw at an event in North Phoenix on 12-21-13. I see your travel bug is still traveling, how awesome. Continued, safe travels!!
