Every week it's getting darker earlier. In winter, the Northwest is pretty much dark after 4:30(!) We're not quite there yet. The sun's hanging in 'til about 6:30 or so. We still get beautiful evenings where the sky is a deep midnight blue, or the clouds turn rosy pink as the sun sinks down.
Here's a line of trees in shadow with some dark spots on several branches. Those would be the crow convention that was gathered in the park, hanging out by the man-made creek and waterfall.
