Every year on the 30th of April the Dutch queen celebrates her birthday. The day is celebrated with bands, beer and kids selling stuff on the street.
I lived in Rotterdam from 1990 until 2000 and during those years “koninginnedag” has always been a pleasant party. I would normally watch a band, buy a beer and walk to the next stage to have a look at another band, buy another beer… Oh and there is (almost) always the added benefit of great weather.
That does not seem to be possible anymore. Due to some soccer related troubles, Rotterdam had in the past, you are now no longer allowed to drink a beer in the street. You are only allowed to drink beer in front of a bar surrounded by a metal cage. You are not allowed to leave this prison before finishing your beer (I admit, that is a nice way to spent prison time).
It seems that the beer cage only goes for Rotterdam. I think it is a shame that Rotterdam accepted these rules. Koninginnedag is a day for party.
