Annother problem is, that if you are really in the country, you aren't allowed to take pics of any military things. Which in fact is not that dramatic, because if you act smart with the camera, you can make unnoticed masses of photos - but we have known it just after passing the (very relaxed) emigration controls

Plus the problem, that so many things over there are secrets or taboos, that the local people, even the well-informed guides, don't know anything. Or -which is more common- that they aren't allowed to talk about it. So they say nothing or something wrong (as for example about the origin of foreign cars, especially US-cars. I've asked about that)
