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
3 degrees warmer at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.

The Gateway City of St. Louis is the epitome of the modern Midwestern metropolis. Missouri's second-largest city is vibrant but laid-back, populous but navigable, historic but still relevant. The city's planners have created an aesthetically beautiful city, with plenty of green space amidst buildings both old and new, framed by the majestic Mississippi and Missouri rivers. And capping it all is the world's tallest man-made monument, the beautiful and iconic Gateway Arch.
St. Louis is a city of culture and surprisingly inexpensive. Among American cities, only Washington, D.C. has more free attractions for tourists and residents alike. Hotels, restaurants, and even parking garages avoid the premium pricing common in other big cities. Although often overlooked, St. Louis can be an affordable, educational, and fun family getaway.
