Last year I was headed north on I-24. I had just crossed the Ohio River bridge into Massac (less than 2 miles from the bridge). On the left side of I24 stands a grown doe in a field. On the right shoulder of I24 looking at her was a 180 class buck waiting to cross behind her. That was an awesome sight and it was November 14th, 2007. You should hit the rut just about perfect.
I hunt in Johnson Co. in S. Illinois just N of Massac. I truly believe S. Illinois is a sleeper area for big bucks. I am providing you with pic of a buck from our lease from 2007 (i'm not the lucky guy). I think you'll be ready when you see it!
