No, I'm not the one driving around the Czech Republic. My geocoin is.
Yes, despite my instruction that the coin wants to return to America (instructions I'm happy to see made it into the picture), the coin is still bouncing around Bohemia seven months later, as you can see from the picture below. (Note that the lines leading east are from its brief trip to Kazakhstan). Maybe I overestimated the frequency with which geocachers cross borders.
Despite being in Europe currently myself, I have no plans to drop off any more coins. Based on a brief search, the caches near my hotel here in the UK are either too small or annoying to find. There are very few caches in Istanbul, and I don't feel comfortable digging them up.
