Hi, hope you can all help, we are from the UK and are looking for some US road trip advice!! We are travelling from Chicago O'Hare airport to Green Bay in Jan for the a Packers game. We wondered if anyone had any tips/experience of this route? We have to hire a car and as we have no experience of the weather we really did not know where to start-we don't know whether a regular Chevrolet Aveo they are offering us (the economy option) will be adequate or whether it is derfinately worth upgrading to a SUV or something a little sturdier :) ? Are the conditions of the roads still good at this time of year? We are mainly concerned about the driving conditions but would appreciate any route advice etc!
