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

Detours Along the Way
Tagged by where each one fits in your drive — first break, midpoint, final stretch.
Pomona is in the San Gabriel Valley, near Los Angeles, California. Named after the Roman goddess of fruit, in the 1920s it was indeed known as "the Queen of the Citrus Belt." However, its origins preceded that epoch as an allotment given to two ranchers, Ricardo Véjar and Ygnacio Palomares, in the 1830s, when the territory was still part of Mexico. After the Treaty of Guadalupe Hidalgo and becoming part of the USA, it eventually became absorbed into the megalopolis of southern California, with perhaps its main standout nowadays being the site of the LA County Fair, or the location of Cal Polytechnic U.
