That's a big drop in temperature! Here in Florida, we often have a 20 degree drop during a day, although, thankfully, we rarely get as low as 13F. It has happened. In fact, I remember a Christmas in the 1980s that got down to 8 degrees. Yes, in Florida.

You are a very busy person. Ellie. It's admirable that you manage to fit in the Photo-a-Day!
