Seasonal Notes
Summer travel usually means heavier construction, hotter rest stops, and busier weekend traffic around major cities.
Winter travel shortens daylight, so a route that looks manageable on paper can feel much longer after dark.
Holiday weekends tend to make both departure and arrival windows slower than the raw route time suggests.
Time zone
Same local time
Origin and destination are on the same clock, so arrival timing is easier to judge at a glance.
Temperature spread
8 degrees cooler at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.

On the drive from Chicago, IL to Millstadt, IL, road signs begin pointing toward Springfield along the way.
Chicago is the home of the blues and the truth of jazz, the heart of comedy and the idea of the skyscraper. Here, the age of railroads found its center, and airplanes followed suit. "Stormy, Husky, Brawling / City of Big Shoulders," Chicago is a Heartland boomtown, its ethos defined by urban planner Daniel Burnham's immortal vision: "Make no little plans; they have no magic to stir men's blood." It is one of the world's great cities and the third largest city in the United States, behind only New York City and Los Angeles.
As the hub of the Midwest, Chicago is easy to find — its picturesque skyline calls across the waters of Lake Michigan, a first impression that soon reveals world-class museums of art and science, miles of sandy beaches, huge parks and public art, and perhaps the finest downtown collection of modern architecture in the world.
