NEWARK, N.J. — For all the consternation over whether Mother Nature may or may not visit in northern New Jersey for next weekend's Super Bowl, another unpredictable force could determine whether the event turns into a transportation debacle: the football fan. The $64,000 question, beyond whether Feb. 2 will bring another storm the likes of the one that dumped nearly a foot of snow Tuesday, will be whether the estimated few hundred thousand visitors to the area heed organizers' advice and leave their cars at home or at their hotels. If fans do decide to take mass transit, they will find plenty of options waiting.
