Sort of know what you mean, though we have central heat, keeping it a toasty 67 at night. I woke up to a white-wonderland - no snow, but a heavy layer of frost. It got down to 23 this morning and the next two mornings will be 25. That will make a total of 12 nights in the mid to lower 20's, and we haven't even gotten close to our "cold" months, January/February! Welcome to the Deep South.
