Driving the Garden State Parkway to New York, I pointed out two crows to a woman who believed crows always travel in threes. And later just one crow eating the carcass of a squirrel. "The others are nearby," she said, "hidden in trees." She was sure. Now and then she'd say "See!" and a clear dark trinity of crows would be standing on the grass. I told her she was wrong to under- or overestimate crows, and wondered out loud if three crows together made any evolutionary sense. I was almost getting serious now. Near Forked River we saw five. "There's three," she said, "and two others with a friend in a tree." I looked to see if she was smiling. She wasn't. Or she was. "Men like you," she said, "need it written down, notarized, and signed."
