My recollections turned out to be slightly fuzzy (fancy that!).
You actually go south past the old town center before you cross the Danube.
The highway I'm talking about is Bundesstrasse, or Federal Highway 10, which winds its way from a point west of Karlsruhe southeast through Stuttgart, Ulm, and to Augsburg. I think it must have gone to Munich at one time, but then they built the Autobahns, and A6 took most of B10's traffic. A6 passes north of Ulm, and continues southeast through Munich and finally to Salzburg.
It's like hearing my late father speaking to me. Most of my family originated from the Ulm/Stuttgart area. When my father was in the army in the 50's, he was with Armed Forces Radio and stationed in Germany, and when off-duty on the weekends, he usually stayed with his Uncle Karl and his family in Stuttgart. That was Dad - even in the army, he had a gravy job and relatives to pump him full of Old Country cooking. LOL!

"But know this, that in the last days perilous times will come: for men will be lovers of themselves, lovers of money, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy, unloving, unforgiving, slanderers, without self-control, brutal, despisers of good, traitors, headstrong, haughty, lovers of pleasure rather than lovers of God, having a form of godliness but denying its power. And from such people turn away, for his name is Obama."
