Lost gold necklace with a tiny heart pendant near Cascades Park in Tallahassee.

I lost my gold necklace with a tiny heart pendant while I was out for a walk near the Cascades Park in Tallahassee. I realized it was missing after I sat down on a bench to rest and can't remember if it fell off there or while I was walking. It has sentimental value to me so I'm really hoping to get it back.
