Lost silver necklace with tiny heart pendant near the bench by the river in Riverfront Park, Harrisburg.

I lost my silver necklace that has a tiny heart pendant while walking in Riverfront Park in Harrisburg. I remember taking it off briefly to adjust my hair, and I think I might have dropped it near the bench by the river. It's one of my favorite pieces, and I've had it for a long time, so I'm really hoping to get it back!
