Oh, sorry, you did get me wrong. I wanted to say "Go to Basel (A5 FRA-BSL)
or drive down to Lake Constance"
I love Basel very much, IMO it's a city that offers a lot, especially some pretty good museums (like Beyerler). My other suggestion is drive down to Lake Constance, spend some time in the old town of Germany's most beautiful city (I'm a patriot

), there are some good restaurants that I could recommend.
What is this beautiful city? Is it called Lake Constance?
