Urban Forest

Many parts of Vienna have been transformed into forests lately and Graben pedestrian zone is no exception. It looks almost enchanted in the snow: 
In case you were wondering what that is all about, it's basically pick-your-own-Christmas-tree "markets" all over town. After Christmas or by January 6, the (un)official day when everyone takes down the decorations from their trees, which by then will be pitifully dry and devoid of needles anyway, the trees are collected at the same spots which then become "Christbaumsammelstellen". In Vienna, the trees go to the zoo where apparently elephants snack on them.
