Berlin should be a must see for any first time visitor to Germany, although it is a 4 hour train ride away from any other interesting German city.
All of these photos are from a trip that I did over the New Years holiday, 2002-2003.
The architecture in the newly built up area of Potsdamer Platz is amazing. I wonder how dated it will look in 50 years, but it sure looks ultra modern today.
If you can drive along the Rhein river starting off near Frankfurt, you'll see a castle (much like the one in the photo above) around just about every turn.
And yes, there are actually a number of Dautermann wineries in Germany. I hope to discover and sample wine from them all.
