One of the coolest cross-country trips a traveler can take is along I-40. The third longest interstate in the United States, the route runs all the way from Barstow, California to Wilmington, North Carolina (that's a 36-hour drive from end-to-end, in case you're wondering). Yet, it’s not the length that makes I-40 appealing for travelers. Rather, it’s the amazing and unique sights that decorate this stretch of highway.
For $429, an Amtrak rail pass lets you break your trip into segments, allowing for stops where you can explore cities along the way. “The train ride from San Francisco to New York can be done for as cheap as $213 with no stops,” Low tells BuzzFeed Life. The fewer stops, the cheaper the ride.
