And it isn't even connected to america...

When I was in Winnipeg in the summer it was pitch black at night so they don't get it.

I was in Río Gallegos and El Calafate once in late January, and to tell you the truth, when it was dark, it was dark. I didn't notice anything strange, apart from the fact that the sun sets very late! I also was in London in late July/early August, and the same happened. So, as someone suggested in this thread, to the non-astronimical eye, this is not noticeable.

You do notice it. There is a blue tinge all night where I live.

The concept of having equal daylight all year is totally alien to me.. even sunsets in summer of around 8pm seem odd.

I goto bed at 3 in the summer not get up at that time..

Saint Petersburg, Russia (60 degress north), is famous for its "white nights", in midsummer there is no real night, only twilight, but it's one of southernmost cities which get this phenomenon.

White nights are ok as a novelty, but I would gladly move my location 5 or 7 degrees south.

If I'm really tired, I can easily fall asleep even at midday. I noticed that darkness cause dark thoughts for me, so I probably would be glad to live in a location which doesn't get really dark in some months. On the other hand, I don't know how to deal with such short days in winter.

Zone which is signed by white letters: white nights (civil twilight), zone which is signed by blue letters: nautical twilight, zone which is signed by letters with color whose name I don't know: astronomical twilight.

Here is a picture i took on 17th June 2012 just shortly before 2 a.m in the morning.

It's of course a bit darker than seen on the picture, but there is always an orange tint on the northern horizon throughout the night at that time of year.
