Navy knit scarf with silver heart pin

I lost my navy blue knit scarf yesterday around 3pm in the parking lot behind the Target on Mount Rushmore Road, Rapid City. It's a Lands' End scarf, about 60 inches long, with a ribbed texture and tassel fringe at both ends. The scarf has a small silver heart-shaped pin near the left end, and there is a tiny moth hole near the middle from wear. It was a gift from my grandmother and has real sentimental value to me; I’ve been wearing it every chilly day since she passed. If someone happened to find it, I’d be incredibly grateful to get it back.
