Waking Up to the Deep Freeze

Well, we definitely woke up this morning to the deep freeze. And in California no less. Felt like I was back living in Minneapolis again! It was 18 degrees just a little after 7 a.m. on the thermometer in the backyard. In comparison, the front yard thermometer, which sits in the shade, read a whopping 12 above zero! (That's how they say it in Minnesota.) And the real question is whether or not I will go jogging in this weather. Any guesses?
