After one night (and our first night on this road trip) in Belgrade, the capital of Serbia, we headed towards the capital of Bosnia and Herzegovina: Sarajevo. We decided to follow our GPS and its suggestion for the fastest route to our first stop on the way; Tuzla. BIG MISTAKE! And lesson learned :-) If we had looked at a regular map, we would probably realised that our GPS planned a route through a corner of Croatia before entering Bosnia. The border checkpoint on the E70 between Serbia and Croatia must be one of the more crowded in former Yugoslavia. It took us more than two hours to pass the border. The one between Croatia and Bosnia at Brčko only took us less than five minutes.
