Lost old violin with scratches inside a brown leather case left on a bench at the state park in Western Maryland.

I believe I left my cherished old violin on a bench at the state park in Western Maryland while taking a break from a picnic. It has a few scratches on the body and is inside a brown leather case. I was so caught up in the moment that I forgot to take it with me. I'm heartbroken and hope someone finds it so I can get it back.
