Me and my boyfriend will be visiting USA for the first time this summer. We have a friend living in Chicago and other around Houston area. We are planning to drive from Chicago all the way to Texas, Houston. Any advise/tips on what is the best way to drive and what are "the must see" places? We both enjoy beautiful scenery and don't really want to spend a great deal of time in big cities, but rather explore smaller villages/national parks and other pleasant places.
Any information is much appreciated!
