Answering my own question here. North Korea is a most fascinating place to visit! My advice would be:
- Recognize and accept you will not have freedom of movement.
- Carry some food... Bars, jerky, peanut butter crackers, chocolate. NK food is repetitive.
- You will have no internet. Period.
- Your photo taking will be limited to subjects that reflect well on NK. Pyongyang is quite "liberal" in this regard, but outside of the Capitol, they mean it. The way around such rules is to use encryption software, or download your questionable shot to a small thb drive. It is your guide who will take the heat...(and maybe you if you stray too far out of bounds)
- Keep an open mind; ask questions respectfully
- If you push the rules, it is your guides who will pay the price,as it is their job to contain you
- Go, enjoy. Engage as many people as you can. Much from the outside world gets into NK ...you just don't know which people are happy about it and which ones are not. And it's dangerous for them to tred into the political arena.
- NK today looks very much like china in 1979. Will they follow China's path? Will they live with the Dear Leader for another generation?
