With temperatures making some cities in the Midwest colder than Mount Everest, Antarctica, and Siberia, be safe!  (-15 to -20 in Chicago not including windchill)

If you're headed out, make sure you bring blankets and other necessities in your car in case you get stranded or have issues.  Bring those portable car jump starters just in case as well.  

Turn your heat up a bit in your home.  A lot of modern homes are not designed for -20 to -30 degree temperatures (Wind Chill -40 to -50) - they're designed for 0 deg outdoors.

Be safe!  And spend a lot of time on 11W and other Buckeye sites.
