We've had zero days. It's been a weird winter and hasn't snowed since mid-December though. For years, our schools never had snow days. Before the 2011 Groundhog Day blizzard, they hadn't had a snow day since the catastrophic 1967 blizzard. Since 2011 though, we've had a couple years with closures at the elementary schools due to excessively cold temps (thank you, polar vortex) since the majority of kids in our area walk to school.
My son is in 8th grade and wants a snow day soooooooooo bad because 8th graders don't have to make up the days, LOL. This winter isn't cooperating so far.
