Read this description of a visit to North Korea. P.J. O'Rourke described places like this in his book Holidays in Hell some years ago.
A Hyundai executive half-jokingly says that his company's excursions are called "Don't Do It! Tours." Cellphones, laptops, telephoto lenses, and powerful binoculars are strictly verboten. Visitors must wear photo ID tags at all times. Photos are forbidden inside the DMZ and in the North. You are not to point at a North Korean, and, in the unlikely event you talk with a resident, you are to avoid any political statements.
Two years ago a South Korean woman reportedly asked a North Korean why President Kim Jong Il was the only fat man in the country, and was detained for several days as a result.
Just another totalitarian paradise, of the Communist variety.
