I am going to be in St. Luis with my family (includes a pre-teen and seniors) for 5 days in late Summer and want to capture all the must-see places around the area. We are planning to include Chicago in this trip. I do not mind driving around for several hours but for something that is worth seeing, of course. We like scenic byways, and definitely do not want to miss city highlights such as Arch but do not care about restaurents/ bars. Please suggest me travel itirinery so that we do not miss best places. Thanks!
