ETROIT, MI - JANUARY 6: Pedestrians cross Woodward Avenue as it snows as the area deals with record breaking freezing weather January 6, 2014 in Detroit, Michigan. Michigan and most of the Midwest received their first major snow storm of 2014 last week and subzero temperatures are expected most of this week with wind-chill driving temperatures down to 50-70 degrees below zero. A 'polar vortex' weather pattern is bringing some of the coldest weather the U.S. has had in almost 20 years. (Photo by Joshua Lott/Getty Images)
