Maybe 317 is directly across from the sign?
A handful of times over the years my local district preemptively closed schools a day in advance. At least two of those times the predicted snow either shifted elsewhere or fizzled out to a mere inch.The thing I notice today is that they will go ahead and close a couple days out, where as when I was a kid they waited until the last possible minute to make the call. You'd have to be ready just in case until about 6:30 AM.
