I went to a conference (ICAPS2011) in Freiburg, Germany but I was not sure I would have the time to go caching, lest not find a rocky cache for this coin. Luckily a dinner was arranged for us at the schlossbergrestaurant Dattler, and I convinced a pack of guys to come caching with me, so that we could drop off this coin. A couple of us was dressed up in suits, and had really bad trekking shoes on, but we made it.
This place is rocky, keep on rocking!!!
