When I was a kid decades, we used to go sledding in the snow approximately every Christmas.
These days snow is such a rarity that my kids have hardly ever seen snow in this country. They’ve gone sledding once or twice in their lives.
Furthermore, the idea of a white Christmas is largely a byproduct of the Charles Dickens era in the late 1800s when he saw snow every Christmas and even skating on the Thames when it froze over.
