Lost black JBL Flip 5 portable Bluetooth speaker near a park in Sioux City, Iowa, inside a blue backpack.

I lost my JBL Flip 5 portable Bluetooth speaker around Sioux City at the park during a picnic. It's black with a durable fabric covering and was inside a blue backpack that I may have left there. I really hope someone found it as I've had it for a while and it's a birthday gift from my friend.
