Americans are usually shocked to see how easy it is in Europe to travel to a foreign country, and how you can travel entirely through a country in a few hours.
But I just realised I never left Spain until I was 21 (and then again I went to Gibraltar). I suppose this is one of the downsides of living in the second largest country in the EU, only behind France. A Coruña and Murcia are at a bigger distance than Maastricht and Milan (and that travel would take you between 7 countries if you wanted to!). Plus being larger simply means there's a greater amount of stuff to see within the country.
Nevertheless, I realise I'm on the minority in this regard. France and Portugal aren't really that far away for most people, plus cheap flights can realistically make anybody able to travel somewhere in Europe if they wanted. So, how surprised would you be if someone from your country told you they never went abroad?
edit: fixed some engrish.
