After a long night's rest you wake up to a wonderful sea of white.
Artist's rendition of your snow day. Even though there's no snow. Bah, close enough.
You have nothing ahead planned ahead of you. The day is absolutely yours.
And if you did have something planned it's gone now, shoo thing that you planned, bad plan.
Snow is everywhere! What do you do?
I would probably frolic for a good hour, build myself a nice fort and stock snowballs for the snowpocalypse then frolic some more. Can never be too careful around snow zombies.
