When this thread started I do not know if they had good websites predicting where they would occur. Here are a few links. Their strength varies over time so the forecast changes to the conditions.

I have seen them in northern Manitoba, Boundary Waters Canoe Area (Minnesota/Canada border) and rarely from southern Minnesota. Once from southern Wisconsin, but that was quite rare.
Winter in Iceland is a spot that some people go to see them.
You often can't see them from cities because the northern lights are not bright enough to overcome the light pollution, even the light from the moon can make them hard to see.
