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.
For long drives, weather on day two can matter just as much as conditions at departure, so check the whole travel window rather than only the first day.
Time zone
1 hour earlier
The destination clock does not match departure time, so double-check hotel check-in windows and late arrival plans.
Temperature spread
7 degrees warmer at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.
Road read
13h 10m on the road
This is long enough that the arrival forecast matters almost as much as departure conditions. Recheck both ends before you roll.

Garland is a city in the Dallas-Fort Worth Metroplex area in the State of Texas. Mike Judge, the creator of Beavis and Butthead and King of the Hill, used to live in Garland, as well as some other small towns around Texas. So, yeah. Don't be shocked if you take a wrong turn through a downscale neighborhood and see someone barbecuing hot dogs using one of those things that turns your truck's air filter into a grill. On the other hand, Garland's north side is a palacial monument to suburban living in all its McMansioned, strip malling, Starbucks-sipping glory. Garland is basically an unprepossessing, pleasant place. While it's hard to get too excited about much that happens in Garland, it is just so darned pleasant.
Moderate complexity with 3 natural rest stops along the way.
