There is indeed a lot of Mjøsa, and I shall see it all as I'm getting the train as far as Vinstra (and then a taxi - reasonably priced! - to the hotel). My experience of the road is that it is dull until a bit up Mjøsa, with a view mostly of brown snow on the verges, but then gets a lot more dramatic. I like looking at what people are doing on the ice. One day I must go that way in summer.

I went by coach overnight from Oslo to Trondheim a long time ago. It was a really long way, but very pretty when we reached the daylight part. I remember having breakfast outside on top of a frosty Dovrefjell as the coach was transformed from the sleeping to sitting arrangement.
