Lost silver flute in a soft black case with a restring sticker at Stillwater park.

I lost my silver flute while practicing in the Stillwater park yesterday afternoon. I remember putting it down briefly to take a break, and when I came back, it was gone. It's in a soft black case with a restring sticker on the side. I'm really hoping someone picked it up and will return it, as it holds a lot of sentimental value to me.
