I envy you your trip.

I have only one thing to add. It seems to be a feature of Polish humor to teach people who don't know the language words and phrases that are not, um, drawing room appropriate. This was a warning from my Polish violin teacher and experience from my grandmother, who taught me to tell my sister that she has a fat butt. (The only Polish I managed to learn) As I recall, during the Carter administration, there was an embarrassing incident, as well.

So, with that one warning, have fun - and come back with pictures.
