You folks who live in the COLD are nuts. I hate going outdoors if I'm uncomfortable wearing shorts and tee shirts. I've had my time living in the cold weather. No thanks. There is a reason that I live where I live. I put up with the traffic, crowds, taxes, politics and every other negative just to stay comfortable outside. We have a/c and heat but rarely run either one. So, with that said, best of luck to you in your 30° weather.
