Found it 03/29/2019.
Back in beautiful Pori again and trying to find some caches. Mmmm, I really wanted to find this multi-cache, but the google translation was very bad. With some logical thinking I calculated a acceptable final location. So I tried to find this cache. There was no one around GZ to hear my "Yes!!!!" when I found the cache. A big smile came over my face when I signed this log. Great! Greetings from the Netherlands!
Thank you for the nice multi and the cache, or as we say in Holland: bedankt voor de cache!
