Lost portable electronic keyboard in a blue case with shoulder strap near Copper Mountain Avenue Park in Butte.

I lost my portable electronic keyboard while I was rehearsing in the park near Copper Mountain Avenue in Butte. I wrapped it up in a blue case with a shoulder strap and must have left it behind when I went to get a drink. It has some sentimental value, and I'm really hoping someone can help me get it back. Please let me know if you found it!
