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

Spokane is the second-largest city in Washington State, and the largest between Seattle and Minneapolis. It is the economic hub of the "Inland Empire", a name used for Eastern Washington and the Idaho Panhandle (pre-dating by nearly a century the use of the same title by a region in Southern California). It is at the north edge of the Palouse, where gently rolling hills of wheat fields end at the Spokane River valley.
