In other news, there's a blizzard warning for the Washington, DC area until 6 pm. Also, "parts of Interstates 81 and 77 have been shut down;" "Area airports remain open, with some flights going out;" "Metro opened for service Saturday;" "the U.S. Postal Service anticipates normal deliveries on Saturday, except where road closures block routes;" and most importantly of all (snark) a few days before Christmas, "Several local mall managers said they were making every effort to remain open on Saturday and keep employees and shoppers safe." I'm not sure how you get to the local mall, but if you can make it there, you can shop 'til you drop apparently! :)
