Trust me. You don't want to drive to the US Open. Driving is a headache. Parking is expensive ($15) and far from the Open, and the traffic can kill your swinging mood. The #7 subway is cheap ($2) and stops a short walk from the US Open. So does the more expensive LIRR (Long Island Railroad). The advantages of the LIRR over the subway are the set schedule, comfier seats, and faster trip from Manhattan's Penn Station.
