In the broadest possible sense, Idaho can be divided into "potato" and "non-potato" Idaho. For instance if you drive US95 through here (the creatively named Idaho County, Idaho) it's almost entirely wheat farms, and what isn't a wheat farm is either forest, wilderness or cattle ranch. The potato part doesn't really start until you get down into the whole valley/flat land area occupied by Meridian, Boise, Nampa, etc.
