As I were waiting for my flight from Düsseldorf airport (NRN not DUS!!), the one where it used to be a RAF Station, I had some time to spend and decided to grab some caches. I followed the gps on my phone into some smaller roads (there were a lot of small roads and a lot of fences) in the direction of a cache. Suddenly a really mad German came running after me, yelling in German that this was forbidden area. I understand German, but I do not speak it so well, so I'd turned around, shrugging my shoulders and said in English I'm sorry and continued talking in Norwegian as I walked by him towards the mainroad. As I came to the gate before the mainroad, there was a sign on the gate, saying no entrance. But who coud see that as it only was visible when you came FROM the "not-allowed" area??!. But it was quite a shaky experience - and I did not try to pick that cache
