Kristin McCarthy, 24, left, takes Benjamin Kline, 9 months, and Aleksander Kline, 3, for a walk in Washington Tuesday, Feb. 6, 2007. "This is about the threshold of cold that I'll take them walking in," said McCarthy, the boys' nanny, "but it makes the day go faster to take a walk and they're bundled up tight." Temperatures were in the teens Tuesday in Washington.
