"Amber fields of grain" -- much more than just a phrase from the song "America (the Beautiful)". It's one of the most common scenes on the plains of North America. There are millions of acres of grain crops planted across the continent and I've watched the cycle of growth and ripening of grains for more years than I care to remember.
Recently while driving through the farm country of eastern Washington state, I passed a field of fully ripened wheat. The farmer had begun cutting the grain at the far end of the field, so I thought I'd stop and take a few photos before it was all cut down.
