I held on until 4 today, but it was already pretty gloomy by then... yesterday the lights went on at 3! Of course, you're a long way west of here so you'd expect more in the way of afternoon daylight... even going to the wolf centre (100 miles away) it seems to be an 8 minute or so difference. 

Here it's partly cloudy, calm, and humid as it has been all day... the grass still has beads of moisture on it from this morning's rain. 11.4, dew 9.3; the high was 14.5, following a low of 10.6.
