‘s Gravenhage is the stylish old name for Den Haag.  In the new tram tunnel I found out that funny clowns in securety uniforms forbid taking pictures! You need a HTM permit they cleam. I never have heard a more stupid remark. Even todays China is more friendly. The trick for would be phtographers is to avoide long senseless discussions; arrive by tram, get out and go into position. Then when the next car arrives take your photograph without flash and get into the just arrived car and leave. Gluck Auf.
