That's not just an expression. It really happens. I've lived through 6 Rexburg winters. I think this is the coldest yet, and it's only December. Good thing Im heading South with the birds. This morning I was walking to class, and my breath froze. Im not just talking the white cloud when you talk. Im talking my scarf and hat strings had a white crystal encrusted all over by the time I got to school. I looked a lot like this guy.
