Having picked my way south east across the corn fields of Luxembourg, a task made a little more difficult by the stiff, cold wind trying to push me back to the capital, it was a relief to arrive at the Moselle valley. Immediately below me, apart from the wide river, were vineyards. Anyone ever knowingly drunk any Luxembourg wine? The temperature must be one or two degrees higher down here in the valley bottom; I am writing this from the quayside where, on a boat in 1985 and then again in 1990 (perhaps the original was full of spelling mistakes), the famous Schengen Agreement was signed… Could do with a coffee. I wonder what language they speak in Schengen?
