Winter and fog!! Gosh that sounds like magic! You know, there is nothing sweeter than being in the cold dressed up really well and capture some amazing nature landscapes with the mental camera. Did you like Finland? Can you clearly see the northern lights from there? If I would live in the nordic countries I would stare at it all night. I would make my bedroom set-up in such a way that I could have a window in the ceiling and I could look at the sky and at the stars.
I was in a very short visit in Tromso and I witnessed the northern lights. At that time I thought that being a tour guide was the best job ever as the sky is never the same. But if you are not properly dressed that job is no longer fun anymore lol. I will forever remember the Geminid meteor shower that I saw. Epic...
