The city I studied in - Münster, Germany. Münster is one of Germany's most appealing smaller cities, with a history, a town center that blends the medieval with modern, and the lively atmosphere that comes from having a university with students.
I can't wait to go back to San Fransisco. I drove this road and driving is a LOT of fun in San Fran, but of course we preferred the trolley cars. The most crooked street in America - Lombard St, San Francisco, CA.
