The photo from Williams Lake brings back memories, as it reminds me of the summer and fall of 2000 in Montana. Smoke from fires to the west got so thick that the sky was brown except for a teeny sliver of blue directly overhead. Also, one evening I was driving home, stopped for a red light, looked up and wondered why in the world the city had installed a second traffic light at the intersection. Then I looked more closely and realized that the "second traffic light" actually was the setting sun, which because of the smoke was the same color as the red light!
