Lost small black USB drive labeled 'Family Pictures' at the park in Owensboro during a family picnic.

I lost a small black USB drive at the park in Owensboro during a picnic with my family last Saturday. It has a label on it that says 'Family Pictures' and contains lots of sentimental photos we took over the years. I really hope someone can help me find it. It would mean a lot to me to get it back.
