TROMSO, NORWAY
Did you know the Norse legend of the Northern Lights tells of the lights being reflections from the shield and armor of Valkyries? In Norse Mythology, Valkyries are described as Odin's female helping spirits, and are depicted as elegant maidens. Valkyries "Choosers of the Slain" don't choose who gets in to Valhalla, they also choose who lives and dies in battle!
PROTIP: Looking to see the Northern Lights? Whenever I fly long haul flights at night, I always book a window seat on the side of the plane that faces north. This gives a chance to see the Aurora Borealis while on the plane, and luckily I have been able to see them many times while flying!
