[Porsche-O-Phile]

Been a long time since I've been in MI but I specifically recall how terrible the highways were. Certainly nothing I'd feel comfortable blasting along on "at speed". Too many ruts, potholes, cracks, etc. to say nothing of the sheer stupidity for doing stuff like that on a busy public road. Maybe the road conditions are better in that part of the state (?) but based on what I remember they're not anything that would contribute to vehicle control in a positive way.
