It's really terrible honestly. My kids had school cancelled THIRTEEN times last January/February. I would say at best, half of those days ended up even being a day I could understand it being cancelled (a couple of days of it being unbearably cold and a couple days of bad snow/ice). The other half ... either light dusting or nothing at all. There were at least 2-3 days where they cancelled because the weather report said it was going to be bad so they cancelled for precautionary reasons and it ended up not even snowing that day.
I feel/sound like a "get off my lawn" old man when talking about it but it really is kind of pathetic. I am all for safety but this goes extreme on the other side. Kids start to think anytime there are bumps in the road, they are going to get bailed out. The way it is snowing right now, they would have never cancelled school for that 30 years ago.
