We're planning a trip to Milwaukee the end of August this year and I need help getting through Illinois, Indiana & Ohio as we're planning on going through NY via Niagra Falls to Canada then to Michigan to Wisconsin via the Fast Ferry (already have reservations for this route). Now to return back to NY (Buffalo), I need suggestions from Milwaukee south and east. I've heard that Route 45 from Milwaukee is good to Illinois, but from there I'm stumped. I hope someone here has done a similar route and can help or point me in the right direction. Maybe I should just consult AAA ? Thanks in advance.
