Jason Parker-Burlingham posted a confusing pictogram so I thought I'd add my own. This is from the path to the beach in Nida in Lithuania, which is at the Lithuanian end of the Curonian Spit. That's the sliver of sand that juts into the Baltic, half of which is a piece of Russia marooned inside the EU.
Anyway we worked out what the pictogram meant after walking on the beach. It means the left path leads to a part of the beach reserved for women only, which we worked out when Des and I were asked to leave. Confusingly there seemed to be lots of nude women as well as the bikini-wearing ones you'd expect from the image. The right-hand path was a general nudie beach for anyone.
