i didn't read all posts but i think Polish traditions are slowly disappearing.
weddings are best example.nowadays weddings are completely different from the ones eg. 100 years ago (read chłopi or wesele).
people usually get catering food, there are more and more djs instead of bands.
can a wedding without disco polo music be called a Polish wedding???
people often invite only closest friends and family(and it's more reasonable than inviting 350 guests; neighbours of your aunts,school friends of your parents and cousins who you never met before)
fortunately there are still traditional weddings and other celebrations but usually in villages or in the mountains
In America my cousins are keeping these Polish Traditionas going.
yeah, among USA polonia too.
