Silver Yamaha trumpet with initials JH

I lost my silver Yamaha trumpet yesterday around 3pm after rehearsal at Falls Park. It's a student model, with light lacquer wear, and there’s a small dent on the bell and a tiny scratch near the valve block. The black case has a red interior and a frayed strap from years of use. The bell is engraved with the initials 'JH'. This instrument was a gift from my grandfather and means a lot to me—if someone found it, I’d really appreciate getting it back in Sioux Falls, near Falls Park on Main Ave.
