A policeman stands guard between a line of New York City yellow taxi cabs waiting to get fuel from a gas station in Midtown Manhattan November 2, 2012. A key pipeline delivering fuel into the storm-stricken New York area has resumed shipments and barge shipments were slowly returning to normal, offering hope for relief from a gasoline supply crunch that has frustrated the region.
