I went by bus from Northern Europe down across Italy and through the whole of Yugoslavia and Greece to Athens (and back) 3 times. The crossing from Italy into Slovenia was always a nightmare. Those border guards always turned the bus inside out and took fucking hours and hours to do it. There was always big cheering when we got out of Yugoslavia, north and south.
That's wonderful that there is no more passport control. I'm very happy for you all
Remind me Lorenzo, where do you live again exactly. Must look in the atlas.
