Sometimes gentrification demands serious thought about hard questions (or earnest, rambling attempts at such), and sometimes you just have to shake your head and laugh. I did the latter a few weeks ago while strolling down St. Marks with some friends. Just before the corner at Grand you have a piece of graffiti on a dumpster quoting Jay-Z's latest homage to his rough-and-tumble place of origin, and on the corner you have a Pilates Co-op.
I can only assume that the tagger was on their way to an advanced pilates class when she or he stopped to pump up fellow classmates with an inspirational message for them to read as they arrived. What other explanation could there be?
