Except for the fact that North Korea is a closed communist country, and you wouldn't be able to get in, because Kim-jong il has everyone in the country convinced that the west is evil, and the fact that the country is so communistic you think people in the country most likely don't have the ability to just go to an amusement park, and hop on a ride. So I believe this is a rare credit, because the dear leader doesn't allow free time.
Also look at every picture on rcdb of that park, how many people do you see?
