The greatest American road trip starts this summer. 2,400 miles. Eight states. One highway. And roughly 330 million Americans have driven past a Route 66 sign, eaten at a diner that looks like it's from 1955, and had absolutely no idea why any of it exists. Today we fix that. Because Route 66 isn't just a road - it was a pressure valve. Built at exactly the right moment, used by exactly the wrong people for exactly the right reasons, and responsible for an entire mythology about what it means to be American. This one is about who built it, who needed it, and why a highway the government killed off in 1985 is still the most romantic two lanes of asphalt on the planet.
