I live way, way up in an extremely remote part of Northern British Columbia, Canada, and Aurora Borealis is a somewhat common experience, and because there is NO artificial lights whatsoever, it is very visible. I'm blessed to be able to sit by lake or simply look out a window whenever I desire and observe it when it occurs.

To boot, my wife is a sky expert, so she researches every day, and can pretty well predict with great accuracy when they will occur.
