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

Between Durham, NC and Flat Rock, NC, road signs point toward Shelby and Asheville.
Of the three cities that make up North Carolina's Research Triangle, Durham has traditionally been the one with the grittier, more working-class image. A city of just over 300,000 residents in 2026, Durham has moved beyond a "tobacco town" with a prestigious university at its center to become a regionally and nationally recognized symbol of urban renewal, gentrification, technology and diversity. Durham's vibrant African-American community was historically pioneering in United States Black culture, from the arts to finance.
These days, the tobacco warehouses and textile mills have been converted to other uses, as Durham has taken on a much more high-profile (and expensive) identity. Thanks to local anchor Duke University, a thriving, research-driven medical and tech industry has taken root.
