Hickory nuts the squirrels left behind

This evening I returned home from the woods with a pocket full of hickory nuts that had somehow escaped the attention of the squirrels, or so I thought. Just a few minutes ago I got out the nutcracker and went through the bowl full of nuts, carefully breaking them open one by one. Not a single one had good nutmeat inside! I guess the discerning squirrels were able to tell this without even breaking them open. I am not so skilled.
