I should have said a while back: first of, Centozlot does not take place in Borki for a couple of years now (at least 3), most recently it was held in Szczyrk in the south of Poland.
But more worryingly, there was no Centozlot this year because of organisational problems, I would not be sure if there is going to be one next year... And even if there is one, the tradition is it seems that they are announced very late, essentially last minute.
