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

Detours Along the Way
Tagged by where each one fits in your drive — first break, midpoint, final stretch.
Camden is a city in Camden County, New Jersey, across the Delaware River from Philadelphia. Camden is a former industrial boom-town that has fallen onto hard times.
Decades of disinvestment and government mismanagement have contributed to Camden's sky-high crime rate, and many of the city's neighborhoods are hotbeds of gang- and drug-related violence. However, the government has begun developing the Delaware River waterfront, which is now a popular and well-traveled tourist destination offering grand views of the Philadelphia skyline and a multitude of activities for adults and children. Headlines about violence and crime in Camden may dissuade many tourists to the Philadelphia area from visiting, but a one-day trip to the waterfront may be well worth the trip.
