This is something that I have never seen before. The corn is usually harvested and cut down before the frost. Since the drought killed the corn early, it was left in the field long after it started frosting. Now the leaves are down and the corn is still out there. Slowly it's being cut down - I'm guessing for silage, but I don't know.
Frost on the corn is beautiful. But I hope I never have to see it again.
