Roaming in the EU after June 15,2015
Having lived in Europe, I was there when my country joined the EU. It was an opportunity to be part of something greater. A dream, an ideal of a United Europe. In its very humble beginnings, A united Europe was to prevent another World War, to bring together the European countries so we would not see anything like we did with Nazi Germany.
The dream, the ideal then became that of an economic power that could rival the US.
For this to happen, European countries would have to harmonize and so a common currency was created. And after that, people from each country could move easily between countries with only an ID card. No passports.
