An interesting discovery. This is off the wall of one of the roadside restrooms. A little local lore.  In 1993 the Nazi had a rally with over 20,000 in Rostock. It was the news of the day around the world and has been echoing over this region ever since.  The majority of the Rostock citizens are very opposed to Nazis and so this says "Nazi out OUT of Germany."  I had heard from a travel guide that this was a theme of many.  Get them out of here so we can get on with life.
