Actually, I RETRIEVED it from GCA389W in Rudesheim --- TB Hotel am Rüdesheimer Hafen. (It did not show in this cache's inventory, nevertheless, that's where it was.)
I planned to bring him to California, USA with me, but I see he wants to remain in Germany and visit all the Federal States. I will hope to find a cache for him during our next few days in Germany and then Switzerland. Hopefully he'll reach his goal.
