Wild geese fly south, creaking like anguished hinges; along the riverbank the candles of the sumacs burn dull red. It's the first week of October. Season of woolen garments taken out of mothballs; of nocturnal mists and dew and slippery front steps, and late-blooming slugs; of snapdragons having one last fling; of those frilly ornamental pink-and-purple cabbages that never used to exist, but are all over everywhere now.
