Navy knit beanie with white pom-pom

I lost my navy knit beanie yesterday around 3pm near Heritage Square in downtown Flagstaff, by the trolley stop. It's an adult-sized beanie, thick rib-knit in navy, with a fluffy white faux-fur pom-pom. There's a small scuff on the pom-pom and a faint blue thread stitched along the cuff. Inside the cuff, there's a tiny blue tag with the initials 'MB'—the only identifying feature I know of. I wear it all winter; it was hand-knit by my grandma, so it has a lot of sentimental value. If someone found it, I’d really appreciate getting it back—it's the one I reach for on cold mornings when I need a reminder of home.
