Used to live in S. Dakota. I do miss the random "free day". Seldom get a snow day here in central Ohio, usually not enough to close down, or it melts the next day. First year or two I was here we had 3 or 4 inches one day and school was closed, anyway at about 2pm people were out and about, and radio announcer started talking about cabin fever. I didn't think you could have cabin fever until you had about 3 days that you couldn't get out. LOL.
Hope you have a good snow day-I think they keep us flexible too.
