Amy, your plane is taking off at 5:10? You'll probably board at 4:50 or so. We get up close to 5:30 anyway, so I will give you a call around 5, if you want so you can be prepared as to what to expect. The airport is going to be on top of things. The city should be on top of the removal but I bet your going to be arriving around rush hour.
But......I'm sure you remember that no one in Chicago can remember how to drive on snow so I'm betting that will be the toughest part. Maybe you should plan on breakfast at Midway airport before heading out.
As much as I'd love to see you in the morning, if the roads are bad, just give me a call to say your not coming my way or I'll be worried that something happened.

to all traveling through any storms.
