I grew up in northwestern Ontario, and I can definitely say that the aurora borealis was so common there that I personally grew sick of it. I remember on many occasions going outside for some star-watching, and the stars would be obscured over most of the sky by the aurora, it might as well have been cloudy.
Mind you, there were a few occasions when the aurora was SO spectacular that I just had to watch. One time in particular, the aurora was incredibly bright and concentrated in the form of a rainbow, composed of a swarm of tiny dots growing brighter and dimmer, and individually changing colour. I have never before or after seen anything like it.
