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

Los Alamos is a small town in northern New Mexico, about an hour northwest of Santa Fe. Its claim to fame is the Los Alamos National Laboratory (LANL), where Oppenheimer and other physicists created the world's first atomic bomb during World War II, concluding the Golden Age of Modern Physics and heralding the Atomic Age. Many of Los Alamos's 12,000 residents work at the laboratory. White Rock, with about 6,000, is a part of Los Alamos, but is separated from the main town by LANL. Nearly all of LANL is closed to the public, but the town has a couple of museums which are good places to learn about the history of the town.
