Thinking of Norwegian winters reminds me there was an article in the Guardian a week or so ago, on that most excellent means of locomotion, the 'sparkstøtting', or 'spark' for short. Apparently, the official English term is 'kicksled(ge)', though that's the first time I've heard it. I've seen a lot of them in Norway, and I suppose they must be used in other Scandinavian countries, as suggested by the 1890 Swedish drawing below, but I've never seen them anywhere else. But then where else has enough snow? I wonder if they were ever exported to Minnesota?
