★★ Another dark and warmthless waste of the year’s longest days. Intermittent rain again, mist again, damp sluggish air in the subway. Sidewalk tables were empty. Water beaded on the seats of the outmost aluminum chairs. A backhoe bucked and dropped clods of dirt into a dump truck. An insistent breeze carried news of industrial cooking, news of feces. In the afternoon, in the sculpture garden that poses as a public amenity, the wind made the silvery grass sway, till a rubber-booted volunteer asked the public to leave.
