The concept of a road trip is as American as apple pie, and yet, devising the “best” U.S. driving route is a bit of a head scratcher. Much depends on time parameters, personal preference, and frankly, how long you want to spend behind the wheel.
Tracy Staedter at Discovery News decided to take on that challenge, enlisting Randy Olson—Michigan State University doctoral student and the man behind the famed (and super helpful) Where’s Waldo algorithm—to devise what you might call the platonic ideal of the United States road trip. The parameters were: It had to hit all of the 48 continental states, every stop had to be a National Natural Landmark, a National Historic Site, a National Park, or a National Monument, and of course, had to be confined to car travel and within U.S. borders.
With a stop in Washington D.C. and two in California, the result is 50 points of all American awesomenesss.

That list starts with the Grand Canyon, but you could theoretically begin anywhere as long as you drive in sequence after that. Staedter guesses it would take a little over nine days of driving straight through, but more realistically is a two- or three-month trip.
For the nitty gritty on how he came up with the route, check out Olson’s blog. After determining the stops, the main goal of the algorithm was to find the shortest distance between points.
Olson wrote to Staedter: "Instead of exhaustively looking at every possible solution, genetic algorithms start with a handful of random solutions and continually tinker with these solutions — always trying something slightly different from the current solution and keeping the best one — until they can’t find a better solution any more."
And whether or not you understand the specifics of how it was created, the map is truly a marvel and the kind of itinerary you'll probably spend all winter dreaming about.
