I noticed two years ago....some German train-enthusiasts (a club) had put together a tour package....just to go and ride for five days around North Korea on their old style trains. German state-run TV sent a crew with them, and they were escorted every step of the way by North Korean monitors. It was an interesting prospective, but I’d have to ask myself why anyone would take such a risk, and possibly get arrested for saying or doing something stupid there.
I didn’t know there were regular tours of NK.
Foolish me, I think doing that is immoral and I couldn’t do it. Go to the slave park and observe them grind under dear leader’s thumb...
