About the Cities
Starting in Garland, TX
Full guide →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.
Arriving in San Marcos, TX
Full guide →San Marcos is a college town in the Central Hill Country region of Texas in the United States of America, about half an hour's drive south of the state's capital, Austin. The site of human habitation for over 10,000 years, it was settled in 1808 by Mexican families, and is now the home to Texas State University-San Marcos.

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