I had the chance to see the Geo-Dragonchild's collection at the 2015 Geocoinfest in Eindhoven. And since he kindly sent me the tracking codes, I am even able to log them as "discovered". It was my first geocoinfest, and even though the geocoins form part of every event, the amount of geocoins at the geocoinfest was immense. There was no way to see them all, so I just strolled along the stands and looked here and there what might be interesting. Besides the coins, I also liked the sunny weather, the lab caches around and the overall atmosphere. What amused me a little bit was the beer, since it was really small (I think 0,2l).
Thanks for sharing the collection with the geocaching community & happy geocaching!
