Trip Plan
Since you aren't dealing with highway congestion, you have excellent flexibility regarding your departure time. Aim to leave during off-peak hours to avoid potential local traffic on the market streets, which can slow your progress. Because this is a relatively short 103.8-mile haul, you don't need to stress about rigorous pacing or long-distance rest strategies. Keep that $15 fuel budget in mind when filling up, as local road driving can sometimes be less fuel-efficient than steady highway cruising. My best advice for this specific route is to keep your GPS active and ready, as the turn-heavy nature of these local roads requires constant attention to your navigation prompts.

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