@mwichary Happy Birthday!!! (according to twitter).
My family and I are thinking of going to Poland for vacation this year. Do you have any advice or any can't-miss things?
(My wife's Dad was born in Kolbuszowa near Krakow; I want to visit Torun for the astronomy history.)
Thanks! I haven’t actually travelled much in Poland. My go to answer and favourite city is Cracow, but it seems you already got that covered!
