I think that when Mario Mario grows old he will push a raft in Poland.
Also these pictures are beautiful but why are you all like "WOW NOW I'LL GO TO POLAND!" seriously go to any country in Europe with hills and that is what they look like. If you like Polish things go to Poland, if you like Czech things go to the Czech Republic, if you like Slovakian things go to the Czech Republic, if you like Austrian things to go to Austria... well, you get it.
I guess what I am trying to say is don't go to Slovakia!
