We're going south and it's getting colder!!

Ok, it's 13 degrees here just north of Mt. Vernon. Illinois.  What's up with this?  We're going SOUTH!
So far, it's been tough, but uneventful.  Tough only until south of Chicago.  Our visibility from Allendale to south of Benton Harbor was about 20 yds at best.  Then an accident on the 80/94 kept us at a 10mph crawl.  Then we missed our 57 south exit and lost about 20 minutes :(  From then on it's been uneventful.  They don't have nearly as much snow here in southern Illinois as we do, but it's going to be frigid for them throughout this week.  Single digits during the day and -10 to -20 at night.
We're heading for Mt. Vernon, Ill, to call it a day.  Thankful to have Sue and Barry staying in our house to paint for us.  Yea! 
Hoping to warm up some tomorrow.
Good night for now.
