You'll never get in from the south, fly around to their northern border with china, you'll have ta bribe the chicom customs guys (SOP there)
Then you'll get in easy, make sure you say you want to pay your respects to fallen dear leader at his mausoleum, and be sure to buy a drab North Korean type suit before you go to the show. They are ALL straight up Batshit fucking crazy there, though I did get laid by a cute, but crazy North Korean gash, who knows there might be a little malnourished half round eye running around overs somewhere now!!!
