a rush of air a car is there hop, hop, hop on the subway! Come along for the ride as a little girl and her mother hop on the subway.  From spinning turnstiles and musicians performing on the platforms to people hopping off and on and lights flashing past in the tunnels, the sights and sounds of the subway have an energy all their own.  Anastasia Suen's sprightly text and Karen Katz's brightly colored patterns and lively perspectives combine for a pitch perfect celebration of an underground train ride, where the hustle and bustle is only part of the fun.
