It is a remniscense of old times. How it used to feel when crossing borders. Sitting in the back seat of the car, pretending to play and trying to conceal the giant tv-set between your legs, while the custom's officer is eyeballing you through the window.
A slight deviation.
We cross the border between Slovenia (EU) and Croatia (soon to be EU) at Brod na Kupi. Then we climb from 250 meter to 720 meters above sea level.
