Back to the news: It seems that there is a firm - or an organisation - which specialises in arranging a kind of "package tour" to Prague for Norwegian school kids.
This is the whole Scandinavia + the UK problem. Few days ago Danish students demolished a Prague hotel.
I think that many people in the Scandinavia have the same attitude to alcohol as a child of an alcoholic (you are or an abstinent or an alcoholic) + plus Norway is a part of the vodka belt, because if you look at the consumption per capita it is pretty low in Norway.
