Pretty similar to what Taiwaned said. Just for a lark, an activity outside, to pretty much guarantee it's fresh off the stalk, etc, etc. Wouldn't see us out there picking more than maybe a couple dozen to bring back. There was this Glutton for Punishment episode where Bob Blummer was husking corn as fast as he could and it was painful to watch.

As to which ones to pick... that was definitely throwing me. Wasn't sure how that would work out at a U-pick for corn.
