Trip Plan
Since this is a relatively short trip under two hours, you have significant flexibility with your departure time. However, keeping a consistent speed on I-29 will help you stay within your $16 fuel estimate, as the highway-heavy nature of the route rewards steady driving.

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