Eight o'clock, and it was still too hot for a walk. With the sun already below the horizon, I still felt as though I were being burned. This morning, there was a brush fire at the bottom of the ridge. It was put out within a few hours, but the smoke from it hung about all day, like a fog bank. In the evening, a few clouds began to form in the cool air high above. An inversion layer. All night, the heat will be trapped. All night, I will be trapped in the heat.
