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

Between Garland, TX and San Antonio, TX, road signs point toward Waco, Denton and Dallas Zoo.
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.
San Antonio is the second largest city in the state of Texas and the 7th largest in the United States. It's the 24th largest metropolitan area in the country. Visited by more than 31 million annual visitors, San Antonio is a beautiful city at the axis of three different geological terrains: Hill Country, South Texas Plains and Prairie and Lakes. There's a lot to do in this city: fine art museums, historical missions and plenty of amusement parks in addition to great dining and lots of drinking. The culture and people are vibrant and interesting. San Antonio's downtown is one of the most lively in the nation.
