>>2826694Iowa has some cool little towns worth visiting if you care about that (Pella, Amana, etc). For /out/ it's mostly in the NE. I'd avoid I-80 as well. It's boring as fuck, filled with construction and traffic and has a shitton of trucks. I found US-30 to be far more enjoyable, barely any traffic, speed limits are barely lower, more hilly and trees. Once you're on the western side of Iowa you have the Loess Hills that are /out/ worthy and stand out. Very cool part of the state, you can walk all along them if you really want to.
In Nebraska do yourself a favor and detour through NE-2 from Dunning to Alliance. Very cool ride, I-80 once again is the most dull drive and boring part of the state. If you can run north at Alliance to Crawford along US-20 you then have lots of /out/ options in the Nabraska NF which is pretty cool, especially when most people think Nebraska is just flat and farms (it's not lmao). US-20 is supposed to be good along it for stuff but i'd only done the very western end of it so idk how well the eastern part is.
