Cheated today :(

I cheated today and just drove my car to work. I spent all last night doing some fun things to my Outlook, but didn't check the weather. I woke up today to 12*F temperatures, which means that the standing water and moist pavement I saw last night would certainly be ice this morning. I'd need knobby tires for the ride, but I didn't have time to swap the wheels onto the Outlook, or my commuter stuff onto the Sorrento that's currently got the knobbies on it. Chalk that up to a lesson learned. I definitely need to check the forecast the night before.
