reason for that was unclear. There was no one other than the driver in the car at the time, police spokeswoman Esther Naber said. Members of the royal family saw the crash and gasped, then quickly sat down as the bus continued driving. The attack caused outrage in the Netherlands, newspapers Friday widely expressing disbelief and suggesting the monarchy would have to change. Queens Day will never be the same, the Trouw newspaper said. The Netherlands always has been proud of their no nonsense royal family. With this comes a Queen who not only cycles a bike, but also mixes with people without obvious security measurements. Is that still possible now the royal family has been the target of an attack ? The Algemeen Dagblad newspaper agreed. What is going to happen on the 30th of April next year ? And will we continue to see the members of the royal family cycling through the canals of Amsterdam or hunting for bargains in the Bijenkorf in The Hague ? Queen's Day is a national holiday in the Netherlands, the Netherlands Antilles, and Aruba. The tradition started in 1885 and celebrates the birthday of the queen. Although Queen Beatrix's birthday is January 31, she officially celebrates her birthday April 30, according to the Dutch government. Queen's Day is known for its free market all over the country, where anybody is allowed to sell things in the streets. Other activities
