Winter Solstice and daylight

The winter solstice was about a week ago and on the longest day of the year, the sun came up before 4 in the morning and "went down" around 1:30, and by "went down", I mean that the sun may have been gone down, but it was like dusk in Oregon, where you could still see easily.  Now, only a week later, both Jeff and I notice that it seems to be darker already at midnight instead.  It feels like it's changing very fast here!

One thing we've noticed is that people here don't seem to stick with any kind of scheduled bedtime up here.  We hear kids (little kids) and teenagers out making noise past 1 in the morning!  And people are up and about until the sun actually goes down.
