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

Dennis is in Massachusetts on Cape Cod. It includes the villages of Dennis Port, East Dennis, South Dennis, and West Dennis. Dennis bills itself as the "Cultural Center of Cape Cod", and perhaps rightly so. It boasts the Cape Cod Museum of Art, the Cape Playhouse, and some really excellent art and craft galleries.
A city of history and tradition, Boston offers a proud legacy of culture, education, and numerous sporting championships. The "shining city on a hill"s independent spirit has been displayed to the world ever since colonists were angry over a British tax on their beloved tea and dumped shiploads of it into the harbor in protest.
In the early 1600s, the peninsula in Massachusetts that would become known as Boston was controlled by Native Americans until John Smith (English soldier, explorer, colonial governor, Admiral of New England, and author) named the area New England to attract European settlers. Boston was founded in 1630 by John Winthrop, making it one of the oldest cities in the U.S.
No other American city has made more of an effort to preserve its history, and you'll find buildings that pre-date the republic dotted throughout the region.
Doable as a same-day drive at 1h 46m. Total distance: 76.6 miles.
