Considering they live in the country’s most walkable city, New Yorkers sure seem to need a lot of gasoline. The fuel shortage resulting from Hurricane Sandy worsened Thursday, leading to fist fights and a mile-long line up the Garden State Parkway. The owner of an Exxon in Montclair told the New York Times disputes on the line got so heated he called the police and turned off the pumps for 45 minutes to restore calm. “My nose, my mouth is bleeding from the fumes. The fighting just makes it worse,” he said. Though city officials warned taxi cab supply will likely dwindle Friday, they announced an agreement with a major supplier will ensure emergency operations have enough fuel to operate.
