Better to live next-door to Sanitation Commissioner John Doherty than right around the corner. The Staten Island street outside Doherty's home was plowed clean on Tuesday - but the dead-end streets on either side of his block remained a snow-choked winter blunderland. There was similarly smooth sailing across the upper East Side, home to Mayor Bloomberg and Cathie Black, the mayor's choice for schools chancellor. No surprise there, snow-weary New Yorkers say. Cabbie Edward Fernandez, the front of his taxi torn off by a Greenwich Village snowbank, wasn't exactly shocked by the disparity in the wake of the 20-inch blizzard.
