WASHINGTON (AP) -- Presidential quips about Washington's supposed lack of winter toughness have disappeared as snow accumulations mounted. Barack Obama had been in office for about a week in 2009 when he expressed disbelief that many schools had canceled classes one day because of ice. "As my children pointed out, in Chicago, school is never canceled," he said then. "We're going to have to try to apply some flinty Chicago toughness." Well, here comes more than a little ice: an estimated 20 to 30 inches of snow in Washington.
