Geovim and I tried to find this cache on our MTB Transalp after dinner, but were not successful. First, we could not match the spoiler picture to the area around GZ. Looking around, we found the place where the picture had been taken,but the monument had gone. Confused by all that, I phoned home and asked what was going on.
We then went back to GZ, but did not find anything. Well, it looked like private property and we did not want to upset peope with our flashlight.
Finally, we walked back to the market place and noticed that the monument had been put somewhere else. We tried all holes to no avail.
