FROM OUR ONE-BEDROOM APARTMENT we peer northwest at a sun moving daily southward. Under a rising invisible new moon the lights of Belgrade (Montana) twinkle like Atlantic City seen from the northern end of the Ocean City boardwalk. Layers of cold air settle in from the mountains, no longer held back by the day. The sky goes from blue to orange and green to jet black. Our windows are open and the chill air infiltrates our living room. I feel it flowing over my left elbow but it is deflected somewhat by what is left of this warm late September day.
