I read today that the EU had just got bigger. Way to go EU. Keep eating your greens.
To quote the Slovak Prime Minister (Robert Fico, a youngster, fair play to him): "From midnight tonight you can travel 4,000km (2,485 miles) from Tallinn in Estonia to Lisbon in Portugal without any border controls."
That is of course true if you don't dare go to an airport. I recently flew from London to Dublin and had my passport checked at least 5 times. And Ireland and the UK have a free travel agreement, as well as both being member states of the EU.
So to recap today we are free to travel all around Europe, so go travel, leave the passport at home, there's no need for it.
