Wow! It's Cold!

I woke up this morning to 17 below 0 temperatures. It may have even been colder then that but that's what I saw on television this morning. And with the wind chills I can only imagine how freezing it is outside. My mom wrote me this morning and said it was 20 below where they live and 47 below wind chills. Yikes! My son had to walk to school this morning, he attends college and when he got there he said they had cancelled his class. That would be pretty frustrating. He was so cold and he said his legs were tingling and almost numb. Pretty unsafe to be outside today.
