I got up one day this week and when I went out to get the paper, I was struck by a scent and a feeling that I rarely experience here. Moisture was redolent in the air, taking me immediately to the south. A heavy fog hung over the trees, obscuring the neighbors, and I took a deep breath to smell and feel humidity that is almost never here, but always present in the southern states. As the morning progressed and the fog hung on, Molly was eager to accompany me on a walk to enjoy it while it lasted. By the time we finished our walk about three hours after I first walked out to get the newspaper, the fog and humidity had dissipated.
