Every neighborhood has some special spots that attract an inordinate number of taggers. One of Park Slope’s is a building at the corner of Prospect Park West and Ninth Street. Not the entire building, mind you, but some stairs on Prospect Park West. They’ve been tagged and repainted and tagged and repainted and…well, you understand the cycle. The latest tagging, which has accumulated after a repainting from white to gray over the summer, has taken a turn for the satanic. We’re unclear as to when the next paint job is scheduled so the taggers can start from scratch again.
