Some schools are experimenting with ways for students to do lessons online during bad weather, potentially allowing classes to go on during even the worst blizzard. So-called "virtual snow days" would ease pressure on school calendars and offer students more time to learn in the winter before taking standardized tests in the spring. But there are obstacles, too, especially for families who can't afford computers or Internet access. (AP Photo/Orlin Wagner)
