Here in Iowa we only buy corn in season. Picked the same day, on the husk for $6/dozen. I won't even touch the packaged stuff you sometimes see off season, and given how rarely I see if I don't think many others will either. In season the farmer delivers half her corn to the grocery store and sells the other half from the back of her (happens to be a girl where I live, other places it was a man) truck on the side of the road.
