Thanks for the tips.

I went to school in Champaign, IL so I am familiar with what you are talking about. I remember riding in a bus back to Chicago during whiteout conditions in February 1991 on I-57. There were cars in the ditch all over the place and they closed the southbound lanes but somehow the northbound lanes were allowed to stay open. I agree that an unplowed snowy side road might be better (where I can go slow and steady) but if I hit the ditch I am on my own. I doubt I would take the locals roads. Hunkering down at a truck stop, restaurant or hotel/motel is even better.
