Well lo and behold, out of nowhere, Barty Boy has suddenly reappeared! Of course, there's no explanation or any way to know where Barty Boy had been hanging out these past 8 years. But regardless, this little episode has completely restored my faith in travel bugging.
So if you've got travel bugs out there that you haven't heard from in years, don't despair. Somehow, someway, a kind cacher will find it and get it moving again.
