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

On the drive from La Union, NM to Santa Fe, NM, road signs begin pointing toward Albuquerque along the way.
Santa Fe, founded in 1607, is the capital of the state of New Mexico and its principal tourist destination, renowned for its confluence of scenic beauty, long history (at least by American standards), cultural diversity, and extraordinary concentration of arts, music and fine dining. With an elevation of 7,000 ft (2,100 m), it is not only the United States' oldest state capital but its highest, sitting at the foot of the spectacular Sangre de Cristo Mountains. And with a population of about 85,000 (2019), it's not the most populous capital, but that's part of its charm.
