I recently drove to Michigan from WA, and back.
On the way to, I went through Illinois. Never again. Horrible traffic, horrible roads, delays, and I had to travel lightly through areas that are known to arrest and detain gun-owners, even if they are doing everything by-the-book. Nothing like being stuck in Chicago bypass traffic for 4 hours in a 700hp+ car to make you decide that you need an airplane...
On the way back, I took the SS Badger from Luddington to Muskegon, and skipped Illinois entirely, and had a far less stressful and much happier drive.
