★★★ A pavement saw screamed and threw gray dust, as water sprayed from its loose hose connections. The gray sky above was getting brighter, with blue and white patterns fading in. The air carried a refreshing degree of dampness. Full sunshine took over; a pigeon and its tidy pigeon-streamlined shadow waddled by. As the sun continued, the humidity lost its refreshing qualities. By evening the gray was back. A drizzle descended, clinging to the building tops. It glowed in the lights of clogged East Side traffic, snarled by presidential proximity.
