Dear viewers, if you are planning a trip to Germany, tell us in advance and we'll go with you with a camera to record your impressions. This week we met up with Hisham Abou Omar from Egypt. He's a doctor in natural medicine and has his own practice in Cairo. He's spending a few weeks visiting Freiburg, and it was there that he set out on a trip to the Titisee, a lake in the Black Forest.
