It’s Day Three of the big smoke. The sunlight this morning is a dull, hazy grey-yellow. A little worse than a typical day in Los Angeles; definitely atypical for these parts. The latest from the fire, up north on the border of Napa and Yolo counties, is that crews have cut lines about halfway around the blaze. The Chronicle ran a remarkable picture this morning — a satellite photo that shows the smoke plume. Impressive how far it stretches.
