Like most of the country, today we suffered through the second day of below-freezing weather. While it wasn't as bad as other areas, to have 12-degree mornings for a prolonged period is difficult in the South. Many fruit trees were lost and pipes frozen. Even dressing warmly is difficult given many don't own a heavy jacket.
In the same sense, perhaps the prolonged cold will kill off some of the pests that plague us in the summer.
