Lost Yamaha FG800 acoustic guitar with scratches found at Jones Beach, Long Island.

I misplaced my acoustic guitar, a Yamaha FG800, while attending a small picnic at Jones Beach in Long Island last Saturday. It's got a few scratches on the back but is otherwise in good condition. If anyone has seen it or picked it up, I would really appreciate getting it back, as it has immense sentimental value to me.
