Keyring with red dragon charm and two house keys

I lost my keys yesterday around 3pm near the Smothers Park gazebo on the Owensboro Riverfront. It's a silver keyring with two house keys and a red enamel dragon charm, plus a small USB drive tucked in there. The dragon charm has a tiny chip on its wing, and one of the keys bears a small heart-shaped scratch I carved when I was a kid. They were a gift from my grandmother, which makes them especially sentimental, and I really need them back.
