Houston's weekend map reaches the Gulf in under an hour and Louisiana in four, which is a wider range than the flatness suggests.
Texas distances are large, which means a Dallas weekend either stays close or commits to a Friday night departure.
Miami's weekends run down a single highway into the Keys or west into swamp, and the two could not be more different.
Chicago's weekend geography is organised around Lake Michigan, and which shore you pick changes the whole trip.
Los Angeles sits within three hours of desert, alpine forest, wine country and the Pacific, which is an unusual set of choices.
New York is one of the few American cities where a weekend away needs no car, because the rail network still works.
Atlanta sits at the southern end of the Appalachians, which puts real mountains ninety minutes away and the beach five hours.
Washington sits between the Chesapeake and the Appalachians, with more history per mile than anywhere else in the country.
The Cascades split Washington into a wet half and a dry half, and crossing them is the most useful weekend decision.
New England is small enough that Boston reaches beaches, mountains and three other states inside two hours.
