Lost silver Armstrong flute with engraved initials 'J.S.' near Macon Convention Center.

I was performing at an event near the Macon Convention Center and must have left my beloved silver flute behind during the hustle of packing up. It's an Armstrong model with a few identifiable scratches and has my initials, 'J.S.', engraved on the barrel. I've checked all the event areas and even asked around, but no one has seen it. I'm really hoping to get it back as it has sentimental value to me.
