If you've never seen the northern lights, it's really worth finding any excuse to go do. Videos can give you an idea of what it's like, but there's something deep in the animal brain that reacts to the sky being full of shimmering, spooky light, that is really impossible to describe or to capture on film.<p>Just like a solar eclipse, the aurora is one of those celestial phenomena that you really have to experience firsthand, at least once in your life. It's worth the hassle!
