I am a member of the amateur road biking team DGD racing team. During our training camps in south tyrol we have collected a lot of information on where you can eat good Apfelstrudel. You can find those information here.

My favorite football (for the American: soccer) is SV Darmstadt 98. Currently, they play in the Bundesliga 2, the second division of professional football in Germany.
