Exit?
In order to prevent its citizens from fleeing, the government has indeed secured more than 1,500 miles of the North Korean coastline with electric fences. Dangerous? Yeah you could say that.
“Guided” Tours
Whenever you head somewhere for vacation or business, chances are, you’re free to roam wherever you’d like! Although that’s not the case when it comes to North Korea. All tours must be, and are, organized by the state. For that reason most tourists only encounter people (citizens) that have been examined by the state. That’s right, they only want you speaking with people who won’t lie. Well, they will lie, but only because it is what is required of them.
