Now, you really caught me with your reply! 😃
I was intrigued enough to go and search for it on the map. By the names shown on the screenshot map that you posted here, I thought it might be somewhere in Poland, but I wasn't sure. Now I am! 🙂 It's quite close to Katowice.

Apart from this whole beavers' story (although, it might sound strange, but I have to tell you), I am amazed how you (the Polish people) managed to get organized, accomplished fast growth and development of the whole country, hugely raised the standard (of almost every average Joe) once the iron curtain was finally pulled off and the old communist clique replaced with "fresh" people in the lead with an entirely different mindset that the ones in the previous regime.
You wouldn't believe how often we talk and discuss it at home!

Therefore, your beavers' story makes even more sense and it's a perfect fit for the whole picture! 😃
