Thanks! No, it's not really hard to get inside North Korea, but it's quite expensive. And when you're there, beware of all the rules - it's still the most authoritarian country in the world, although they're easing up on things at the moment. But it's definitely worth a visit, it'll be like nothing you've ever experienced :) And you'll notice right away that although Koreans have a strict and hierarchical mentality (especially in North Korea), they're also very polite and friendly. It's certainly not impossible to get in contact with locals either.
