@ CT Lawyer I am sorry to hear that you were inconvenienced. In your situation, I agree school should have been canceled.
I live in Five towns where three of the local girls school and one boys school canceled (-that I know of). They canceled in the morning while it was still raining and snow was not predicted to fall till about 1 PM. Turns out we got one inch of snow….. Everyone who works still went into the office…..
