It is a common misconception that Norway has what is called "Midnight Sun" during summer. In fact, it is only the very northern parts of Norway that has this. Where I live, during the brightest days of summer, the sun sets about 2 in the morning and rises at 4... Further down south, they don't even come close to this.
I spent a year, doing my military service up north, and I found the midnight sun very unsettling, and I had trouble sleeping.
Regarding costs in Norway, yes, it is a very expensive country to live in. But, of coure, salaries reflect this, and living here is a very comfortable excistance indeed. I guess it's hardest on the tourists. Anyway, if you have any questions at all about Norway, feel free to PM me, and I shall answer to the best of my ablility.
And to my compatriot, Hege: Halla! Fint å se en annen nordmann her
