Lost Yamaha PSR-E373 keyboard, gray with black stand and engraved name, near Fairhaven Park in Bellingham.

I lost my Yamaha PSR-E373 keyboard while I was at Fairhaven Park in Bellingham yesterday. I remember packing it up before I left, but I must have left it behind while I was talking to a friend. It's gray with a black stand and has my name engraved on the back. I'm heartbroken over it, as it has both sentimental and monetary value.
