First visitors!

 Our first week long visitors were my brother, Jason, and my new future sister in law, Sara.  We took them to all the Berlin sights including a very old sight, the Brandenburg gate, which was one of the gates to the Prussian city in 1791 and then later part of the old Berlin Wall between East and West Berlin in 1961-1989:

 

Other newer Berlin sights like the Holocaust memorial, built in 2005 to commemorate specifically the murdered Jews of Europe by the Nazis in the 1940s (there are other memorials planned for other targeted groups of the Nazi regime): 

 

And, of course, the oldest beergarden in Berlin, the Cafe am Neuen See:

  

And the beergarden that sells "one meter beer": 

 

And, most importantly, the Potsdam Abenteuerpark.
