I live in Central NY, and we’ve had snow storms in May, and in October. For several years in a row, we had snow storms on Halloween. They make it sound like these things have never happened before.
I spent five years (ages 8 - 13) in Ithaca, NY. Trick or Treating in snow was not unusual in the 60s.
But to get this storm a full month before Halloween...wow. Like the article says, only the fourth time in recorded history in Coeur d’Alene.
