>>2794446I've done the east to west US road trip on 4 different routes multiple times. There is nothing worth seeing in Iowa, Oklahoma, Nebraska, The Texas Panhandle, Kansas, Missouri, Indiana, Ohio, Alabama or Mississippi. You waste at least a week driving across flat farm land that smells like cow shit. St Louis is so dangerous you won't stop to see the arch.
The best things to see in the US are on the east and west coasts. People get this idea that they should go east to west, when they should be going south to north on the coasts.
Start in San Diego and drive up through Vegas, the Grand Canyon, Sedona, Zion, Bryce National Park, Arches, Moab, Telluride, Durango, Taos and then Santa Fe.
Or drive up from San Diego to San Francisco, Yosemite, Lake Tahoe, Lassen, My Shasta, Bend, Mt Hood, Rainer and Seattle.
Pick any section of the 101and just drive up the coast and it'll be the most beautiful drive of your life.
The drive from Salt Lake City through the Tetons and Yellowstone is utterly insane.
If you have to go east-west, go Chicago, Rapid City, Yellowstone, Missoula, Coeur d'Alene, Seattle.
