Longest Day of the year

Sunset here today was at 10:07 pm, now it's just after 11 pm and still twilight (ie. not fully dark). I remember when I was in Peace River in 1998 for part of my residency, in June it was still twilight even after midnight when I'd get called back to the hospital while on call - I think there it got dark about 2 am for a couple of hours only. These are the days I long for in December when it seems like it's dark all the time ...
