Route 66 might be known as America's Mother Road, but U.S. Route 20 is, without question, the Big Daddy. It's America's longest road, stretching from Boston, Massachusetts to Newport, Oregon. That's 12 states and 3,365 miles to explore. Go big and then go home with a mega road trip along this epic route.
Driving across the whole country, you're bound to pass tons of classic American stops. Start in Boston, and honor the American Revolution with a visit to the Old North Church.
The route also wanders through Cleveland, where you can jam out at the Rock 'n' Roll Hall of Fame, and then passes through Chicago, where you can get a crazy view of the city from atop the Willis Tower (better known as the Sears Tower) and brush up on your architecture knowledge at Frank Lloyd Wright's house.
Once you reach Iowa, you'll see a lot of cornfields, but there's one in particular to visit: the one with the baseball diamond from Field of Dreams-- don't forget to bring a glove, bat and baseball.
Also visit the Lewis and Clark Interpretive Center in Sioux City and be thankful that your cross-country road trip is a bit easier than theirs. In Nebraska, imagine what the country looked like millions of years ago and check out the fossils at Ashfall State Historical Park, and then appreciate the uniquely American weirdness that is Carhenge.
U.S. 20 passes through Cody, Wyoming, named for Buffalo Bill Cody, so the Buffalo Bill Museum is a must. You'll also want to stop by Yellowstone National Park and its neighbor, Grand Teton National Park.
Once you finally, at last reach Oregon, celebrate with a pint at Deschutes Brewery (one of America's first craft breweries) and a warm bowl of clam chowder at Mo's Restaurant. There's nothing quite like dipping your feet in the Pacific Ocean after an exhausting but exciting 3,000 mile excursion.
