Snow!

Well, this is the first snow I've seen since moving to Maryland. It's supposed to be all icy and stuff tomorrow, so I'm not looking forward to the roads being crappy. I noticed in the parking lot at work that a lot of cars had their windshield wipers sticking up. I can't figure out what the reason is for it. If it's to prevent them from freezing to the windshield, wouldn't it make no difference, since then the windshield would just have ice on it and the wipers not work anyways? I don't know. If you do, let me know :)
