Absolutely: if you have a car available...
The farming landscape west of Spokane is amazing; just go out there and drive around. There have been a number of photo books shot in the area, and some of the best landscape photography is done there; but it's not one place -- it's sort of all over the place. The only thing I can think of that it reminds me of is central Italy, but in a much broader, American style. I drove through there last summer on a really hot day, and there was a farmer out working with a tractor, kicking up a lot of dust. The dust was picked up in a dust devil (whirlwind) that must have extended 500 feet over his head, this giant tornado-like thing following behind the little green John Deere tractor. We saw a couple of dozen dust devils that day...
In a more subtle way, it's a landscape as engaging as any of the canyon country or New Mexico landscapes, in my opinion. Just take I-90 west out of Spokane and then wander off to the north...
