@jon357 It's not that easy, Częstochowa lives off of pilgrims. But to be a pilgrim, you have to believe in something and that's what religion lessons are for.
Krakow is a "must have" for every foreign tourist in Poland. Warsaw is less interesting for tourists. I am no expert when it comes to nightlife, but others on the Forum are.
@Itay I'm assuming you're female due to your fragmented response. If so, I understand that you are fascinated by your Polish great-grandmother. Unfortunately, great-grandmother is not even grandma. The time factor is simply too far away. Was it now an acceptable answer?
@Itay Sorry pal, I have a mathematical approach to reality. Your question was: am i polisch. There is only one correct answer. No you are not Polish. Not, even if you are a nice guy.
