C-c-c-cold...

The chill in the air today reminded me that I will have to invest in some warmer attire soon. As a life long resident of upstate New York, I am no stranger to bad winters, but I have a feeling I've seen nothing yet. I am currently looking at Timberland and Columbia's websites to find durable, warm jackets and good boots. Any suggestions? Especially from anyone who has lived in or visited Chicago in the winter.
