The Guinea Pig says: Wheat, wheat, wheat!
I thought I had seen a lot of wheat fields in North Dakota, but Eastern Washington figured out that the way to get more wheat per acre was to eliminate everything else, including roads, buildings, trees, brush, rocks & water. For miles and miles you see nothing but golden fields. It’s rather awe inspiring, actually. I found myself humming “America the Beautiful“, one of my mother’s favorite Campfire Girl songs.
