It's New York City !
We have 24 hour a day, 7 day a week service. The problem lies in the reliability of that service. It is always running, but not always at the speed that you need it to. The cost is $2.25 a ride, and the subway stops at the main college. Most students commute within the city, and others from surrounding areas. Those coming from outside the city might pay more, and have more of a problem with timeliness in inclement weather.
