John, very good selection. Many of these sites are inherited after Germans, therefore they are not even know very well in Poland - like a skull chamber. I saw Wang Church during our trip in Sudeten. All Polish people know about Wieliczka Salt Mine and also some foreigners. Still, a good selection.
Two days ago I presented info to my weight loss class about Polish and European food habits and why it is easier to stay slim in Europe: walking, food portion, celebrating food rather than inhaling fast food. I showed some pictures of Krakow - and then somebody said: I think I heard about Krakow since it is near to this... concentration camp? It was so frustrating to hear that everything about Poland is... the HOLOCAUST. Nothing else matters.... not 35 mln Poles and a long Polish history.
