It’s springtime, and the cherry trees are about to bloom in Copenhagen Northwest, which is usually the only time people who live outside Northwest bother to go there. Northwest is a working class neighborhood, so much so that the streets are named after working-class occupations. While other Copenhagen neighborhoods have streets named after kings and queens and generals, Northwest has brick-maker street, and book-binder street, and rope-maker street, and a barrel-maker street.   But there are other things to see in Northwest besides the cherry trees, which have become a bit of a crowd scene since they were reported on by a national news network.
