★★ Dimness laced with occasional unexpected colors. Morning was mild, though the sun was weakened by clouds. The air smelled of dampened leaves. Within an hour or two, it was fully overcast, thick and yellowish. The leaves on Prince Street had turned, in their passage through autumn, to the pale green of new spring growth. Spots of pink appeared in the otherwise gloomy late sky. The 1 trains were running 10 or more minutes apart, but walking was a decent enough option, as the clouds went to iodine purple.
