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

Few American cities can match the youthful spirit of Portland, "The City of Roses". The largest city in the state of Oregon, Portland's residents are proud of their city, which draws people for its scenic beauty, great outdoors environment, excellent microbreweries, and eco-friendly urban planning policies, as well as a reputation for colorful characters and a proudly liberal outlook with an attitude to match.
Lying about 70 mi (124 km) from the Pacific Coast on Oregon's northern border, the city straddles the Willamette River (pronounced will-LAM-ett; just remember the rhyme "It's Willamette, dammit.") south of its confluence with the Columbia River. To the east, majestic Mount Hood forms an inspiring backdrop for Portland's skyline.
