Ours is a little different. I was working in West Germany as a DOD civilian for the US Air Force, and was able to put together a long 4-day weekend to travel to Berlin, back in 1990. We did so because this was the weekend Germany was going to reunite into one country after so many years divided politically, and geographically into East and West, so it was a momentous celebration, and the culmination of the Wall being first breached about 3/4 of a year earlier...
Our own particular uniqueness is our claim that we can never leave East Germany or East Berlin...never. The reason is that at Midnight of October 2nd, we were physically standing on the East side of the Brandenburg Gate as October 3rd began. At that minute East Germany ceased to exist, and from then on Germany was wholly Germany. Pretty cool if you ask me, and yes the celebration was an awesome spectacle, yet for many people there, there was a lot of intrepidation too. Many in the East were now officially out of work, with the Russians leaving, and many in the West were fearful of taking on all the debt from the East, and that it would cripple their economy. With 20/20 hindsight it all worked out, and even here in the US, Helen & I are still trapped in East Berlin forever...
