All of LIRR's lines were not running on Monday either, though most were. As the previous poster suggested, the parking may not have been in good shape, also the sidewalks may not have been cleared. Even though there was a whole day to plow before rush hour on Monday, you had to expect a lot more traffic or "choke points." There were still many areas where for example, on a 2 lane ramp, one lane suddenly disappears because the plow did not quite reach across the whole roadway yet. I traveled on campus to Rutgers that Monday and aside from the above icky areas on the road, the parking lot was a disaster. Fortunately I found a spot (along with a colleague) in about 15 minutes. One should not have expected a perfect commute.
DANGER - DO NOT GET OFF MOVING TRAIN
