I don't know how they do it in the cold states either. I live in Florida and it is always warm here. We just had a four day "cold" spell where we dropped down into the 40s at night. Got to wear my jeans for a couple of days but back to shorts again! Sunny and beautiful out today! Kallie loves the cold and it is hard to keep her inside. She loves to lay on the lanai by the pool and watch the golfers go by......Toby is different, he prefers to be inside when it is cold out.
