Snow in Portland

It hardly ever snows in Portland.  Two years ago, when we had just arrived, it snowed for the first time in eleven years, even on Chesil Beach which is covered in salt.  The children in the primary school had only seen snow in pictures.  Now, this year in the middle of January it snowed again.  We haven't even been here for three years and already it's snowed twice.  Could this be down to our Canadian heritage?  Friends advise us to keep quiet about it.  We could get attacked in the street, the weather we're having.  Luckily our accents have all but faded and we hardly ever wear our mukluks, although now is the time we need them most.
