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
The destination clock does not match departure time, so double-check hotel check-in windows and late arrival plans.
Temperature spread
Both ends of the route are sitting at about the same temperature right now.
