Lost silver flute in a black case near the outdoor amphitheater in Grand Forks.

I lost my silver flute in a black case while walking near the outdoor amphitheater in Grand Forks. I believe I may have left it on a bench or maybe even dropped it while I was setting up to practice. It's quite valuable to me as I've had it since high school. If anyone finds it, I would really appreciate it if you could reach out!
