Going through Checkpoint Charlie to the Soviet Zone in a very shiny black Range Rover, and getting the tour. Drove up onto a rubbish tip to get a really good view of the barracks below. Looking at the faces of the East Germans, in their Trabbies, looking up at the RR as if it had landed from Mars. Watched the changing of the guard - squint slightly as they goose-stepped along and you were back in the 30s...
Had to wear a beret and shoulder tabs from one of the Corps - oh the shame of it
