Navy knit beanie with gray pom, lost in Quad Cities

I lost my navy blue knit beanie with a gray pom yesterday around 3pm. It's an adult medium, rib-knit, with a tiny embroidered white snowflake on the cuff and an inside label that reads 'Horizon Outdoors, M.' I think I dropped it while walking from Vander Veer Botanical Park toward the riverfront trail in Davenport, near the duck pond. This hat has sentimental value—it was a gift from my grandmother and is the last warm thing I have from her. I really need it back and would be grateful to anyone who finds it.
