Snow days are rare in my state, but in case you have one, don't be bored!
1. Go sledding
Find your local hill, if possible, make sure it's within walking distance if the roads aren't in favorable conditions.
2. Sleep in
This is more aimed towards the teens, but who doesn't like sleeping in?
3. Drink hot cocoa
Seriously though, hot cocoa is great. It's even better on a cold snowy day.
4. Binge watch a Netflix show
Most people do this on any normal day, but the snow day gives you even more of an excuse to do this. So, why not?
5. Play video games
I know not everyone plays video games, but a snow day is a perfect time to binge on your favorite video game.
6. Have a movie series marathon
Have a "Star Wars" marathon!
7. Read
Have a book you've had laying around all year? Get it done! There isn't a better time.
