Found sunburst Yamaha FG800 acoustic guitar

I found a sunburst Yamaha FG800 acoustic guitar this afternoon around 4:15pm, tucked under a bench near the Port Townsend ferry terminal on Water Street, in the Olympic Peninsula. The guitar has a couple of scratches along the lower bout and a light coffee stain near the pickguard. The case is a black hard-shell with a red velvet lining, and there's a faded sticker of a lighthouse on the inside lid. There's a blue strap attached to the strap button and a small handwritten note taped inside the lid that reads 'M. Rivera'. If you recognize it, I’d be happy to return it to its owner—we can meet near the ferry terminal or in town to get it back.
