It's Called "Breakneck Pace" for a Reason
Welcome aboard the RoadTrip America Forums!
Wives have a way of making one grow up in a hurry, so listen to her. As just one example: On your previous RoadTrip did you visit the Petrified Forest or just drive on by? Did you visit Meteor Crater or just drive on by? Did you visit the Grand Canyon or just drive on by? Did you explore the longest remaining piece of the old Route 66 or just drive on by? Did you visit Hoover Dam or just drive on by? Did you visit Oatman where donkeys roam the main drag of just drive on by? Did you stop to see the original, real London Bridge or just drive on by? And that's just some of the stops you could have made in just one state, Arizona. Hopefully on this trip you'll get to do more than simply sit and burn gas and see the inside of a motel room for a few hours.
I-80 is a perfectly good route to take, and makes navigation incredibly easy. Just allocate the time required to actually stop and see some of the things along the way and you'll be fine. Just to list a few of those things: the Amana Colonies in Iowa, the vestiges and landmarks of the Oregon Trail as you follow the Platte River in western Nebraska, Rocky Mountain National Park (a short detour) in Colorado, Flaming Gorge National Recreation Area, Dinosaur National Monument (another short detour), the Wasatch Mountains, Salt Lake City and the Great Salt lake, Bonneville Salt Flats, Virginia City, Lake Tahoe, and Napa Valley. But you can't do any 'of that if you try to make the drive in two, three, or even four days. Actually appreciating the land you'll be driving through will take 5+ days. make sure you have them.
