VIP Desert Sun festival ticket - Yuma

I lost a purple VIP ticket for the Desert Sun Festival. I last had it yesterday around 3pm after leaving the Desert Sun Arena near 32nd Street and Main Ave in Yuma. It's a single-entry ticket with a purple holographic Desert Sun logo at the top, seat info 'Section Orchid, Row 5, Seat 8', and a small tear on the bottom-right corner; the ticket is still in good shape otherwise. It was a gift from my sister, so it has sentimental value and I'm really hoping to get it back.
