The family is coming to the Nationals with me. We want to travel to New York City and back while we are there. We will have a car but don't want to drive in. How easy is it to get transporation into the city from Piscataway ? How long does it take? What is the best way to go? Train? Bus? Any suggested web sites? Any special deals we should know about? Multiple-day passes? Any safety considerations to ponder? Anything else you can think of that would be helpful would be appreciated. Thanks.
