Sincere and heartfelt thanks (viele Dank) to Lis and Frank for the many hours that you spent showing us your most beautiful and historic city. The day that you both dedicated to us gave us a better understanding of the German culture, history and the magnificent section of Munich that you choose to share with us. Spending time with you both was certainly the highlight of our three weeks in Italy, Switzerland, Lichtenstein, Austria and Germany. Speaking with you and hearing your ideas and philosophy will always be a cherished memory.
