I read the following title in one of the newspapers:
Neue Parkvorschriften im Simbacher Ortskern
In my workbook it says that town names do not have a definite article if they are unmodified - so why does it say im Simbacher? Shouldn't it be in Simbacher?
And another question:
Spittal an der Drau
Frankfurt am Main
What's the difference (I assume it has something to do with the exact location of the place)?
