Years ago, a friend and I were driving from Oregon to British Columbia. It was late in the summer; all kinds of local fruits were in season in Washington and my friend bought some every time we stopped.
When we arrived at the border, she had eaten all of it except one peach. The Canadian inspector asked if we had any fruit, and my friend was furious with me for admitting that we did. But the real problem was that, having admitted to possession of a Yakima peach, we couldn't find it in the car.
