★★★★ The gamble on opening the window to the muggy night paid off with clean new air by morning. Light passed through the open top and windows of a yellow jeep in traffic. The breeze counterpunched the heat of the sun, holding its own even in disadvantageous open spaces. Only down in the subway were conditions irredeemable. Where the commuter train came up into New Jersey, the waterways through the heavy phragmites were solid glowing green with duckweed. Some triangular facet of a skyscraper on the West Side was catching the sun to call more attention to itself than it deserved. Insects buzzed and birds sang in the calm suburban streets. Grill smoke caught the rays of the lowering sun. An even, cloudless pink tint made its way slowly up from the horizon. From the returning train, the trees made a solid, wavy-topped wall, and then even that detail was lost in the darkness.
