We've had a number of days of heavy snow here in the Washington area. The depth is something over two feet [60 cm] many places. Remember that we are in the South and this is rather unusual. Public transport isn't running except for the underground parts of Metrorail.

SUITLAND, Md. - Part of the roof and a wall at part of the Smithsonian Institution's Museum Support Center in Maryland has collapsed. No artifacts are thought to be damaged.
The collapse was discovered early Wednesday morning at the Garber Facility in Suitland, Md., which houses artifacts from the National Air and Space Museum.
