Fog

My oldest's class went on a field trip yesterday. They had to be at school at 7 a.m. to leave. It was still quite foggy at that hour. The sun was just coming up, so the light was indirect and low. As we came up the hill of his school's driveway, the building appeared to be separately enveloped in a protective mist. From the backseat, I heard an impressed voice murmer, "Whoa, a force field. Cool."
