It's hard to know what an "excursion" is! We certainly got some nude time in Wales, Switzerland, Austria and Germany. If we count "days when freerange nudity occurred" then it was 3 in Wales, 1 in Switzerland, and 7 in Austria. In Germany we just visited outdoor nude swimming locations, on 3 separate days, plus one factory-farmed place. Do we really have to call the municipal nude beaches in Munich "factory farmed" too?
