Thanks a lot :-)
We also visited Casablance for one day on a layover to Fes. I went to the big Mosque. Have you been there? It's a really impressive building. Otherwise I didn't think Casablanca was very interesting, but I didn't go to the Medina. In the other Cities the Medinas were mostly spices, clothes, leather, lamps, interior an so on. I didn't see animals beeing sold other than chicken. You have the typical butcher here and there but nothing too bad. I'm glad I didn't visit the Medina in Casablanca then. I wouldn't have been able to stay long too.
