My husband has a geotagger attached to his camera, so he can pretty well document where we traveled in Berlin. As you can see, we were in East Berlin almost exclusively. One day we went to Spandau to see the Zitadelle Spandau, and we had to change trains in Charlottenberg (hence the one hit there).
This is basically what I see whenever I travel:
