Subject: Vienna
Dave, I notice that Vienna is one of your destinations and that among your interests are art galleries. You might want to visit the Kunsthaus Wien there. It houses the work of Friedensreich Hundertwasser. (I'm sure there is a web site for the Kunsthaus or for Hundertwasser). You can easily get to the Kunsthaus by streetcar. Have a wonderful - and not too exhausting - trip. Howard in Vancouver
