"A cow!"

Yes, he did. Three heifers, in fact, that were doing some munching of their own. (Thank goodness our garden isn't in yet; the overnight temperatures have been wickedly cold.)
First Son and First Daughter thought they were ours to keep. They were a little disappointed when I said they'd have to go back to their own farm.
We called around and Kansas Dad even knocked on the farmer's door, but we never reached anyone. Eventually the heifers wandered back through another farmer's wheat field and we haven't seen them since.
