The Balkans

At first i saw these trees everywhere in the Balkans. Then i saw them in Vienna - but Vienna is where the Balkans start. Or even more - it is the capital of the Balkans. Then later i saw these trees in the Netherlands. I was disappointed, but well - NL is the center of globalization. And then! - then i saw these trees 40 meters away from my home in Tartu. Robinia pseudo acacia.
