An urban forest

For years I’ve been photographing the ever-changing assortment of street art on the Wall at Central Square in Cambridge, Massachusetts, but this is the first time I’ve ever seen an urban forest of graffiti trees there. Usually, the trees I see outlined on brick walls are painted by shadows, not by spray cans.

An urban wall of bricks is a bit like a forest of trees, each individual fitting among its fellows to create a larger, stronger structure. A quick walk around Central Square on a brisk Sunday morning reveals more than a few trees finding shelter in the city, undeterred by walls and fences.
