There's something about New York in October — the city wears autumn like a costume. Central Park becomes a canvas of red and gold, and there's a crispness in the air that makes walking feel like a gift. I've visited in every season, and while summer's energy is infectious, it's the shoulder seasons — May and October — that reveal the city's true character. Winter is brutally cold, but the empty museum lines almost make it worth it.
