I've had two bugs that bit the dust. One traveled, made it's way back to the area, and I noticed that it had changed. It was named Round Metal Ring Thing (it was a round metal ring from hardware store). Apparantly the chain came off, and the tag was lost. Someone ressurected it (don't know how without the tag), and taped the tracking number onto a metal cap. I went to the cache it was in and retrieved it. Yes, it was mine, but with a transmogrification. Well, I set it free again. And the cache I let it loose in, got plowed over with a backhoe! Oh, the horrors! That cache site has been muggled and plowed more than once. I bought a new ring, attached it to the copy tag with a split key ring, and hauled it around a bit with me before letting it loose again. And then, someone took it to Geowoodstock this year! Yeah!
I don't know what happened to the other bug, which just happened to be related to the round one. This one was Flat Metal Ring Thing. And yes, bought at the same store. Got another flat ring, attached the copy tag with a split ring, and away we went.
Both are still moving, thankfully.
I spent a year, thinking on what I wanted to release, and have since let loose things that I hope don't turn a fancy to others (especially the little ones). One of my first bugs, HighTechHighTouch Flyer, is debatable on whether it is still alive. We do worry about our beloved travelers, though, don't we?
