The afternoon light of an Indian summer day in October. There is no other time of year that is as marvelous and sublime. At a nature center in the suburbs near where I will go to hear Patti Smith on her M Train book tour (a surprisingly nice auditorium on a college campus), I see a coyote in a cage pacing back and forth and I want to set him free. Then I see the barn owl, looking miserable in his cage and really get angry. A nature center, of all places, should not be confining creatures. River Forest park preserve: Shame on you.
