Must-see stops between Cleveland and Portland, OR?

[Tiki]

We traveled from Seattle to Cleveland area last week via mostly I-90 (up to Iowa) then I-29 to I-80 making a stop in Ft. Wayne on the way to the Cleveland area. Stopped at Mt. Rushmore, Wall Drug, Corn Palace.

Route back west will be to Portland, OR. Wondering what the must-see's are that we should route by.

Welcome aboard the RoadTrip America Forums!

You might consider using I-80 through Iowa and Nebraska, then turning north out of Rawlins, WY on US-287 to come up through the Grand Tetons and Yellowstone. If you then leave Yellowstone to the west on US-20, you can connect via I-15 and I-86 to I-84 for a very scenic drive down the Snake and Columbia Rivers into Portland.

Thanks for the tips!

We're heading back west tomorrow, and excited about seeing new scenery.
