I am flying to New York from London with my husband on 23/07. And our return flight is on 03/08. We are planning spend a day or two there and then rent a car and drive to Chicago via Niagara Falls and Toronto. Then we would spend a day in Chicago and drive back to NY taking a more southern route. I have had a look on which routs to take, and am still not sure what's best. We would like to drive along some scenic routes, and I would appreciate some advice, please. I am especially not sure of the way back from Chicago to NY. Thanks.
