I'm not sure if I am going to Sno* Drift, I don't have snow tires and the Rally in the 100 Acre Wood is end of next month http://www.100aw.org/
It's the same distance from Chicago, a LOT warmer and you'll have another month to plan and find a place to rest.
My favorite way to enjoy the rally is Volunteer!!
You drive out onstage with a line or cars (yes you get to have some fun)
Close the road when time comes, basically you sit on the side of the coarse all day and watch the cars go by with your buddies, build a campfire, enjoy yourself.
And sometimes Thank you for donating your time swag.
