Grey North Face backpack with red zipper pull

I lost my grey North Face backpack yesterday around 3pm near the Yellowstone Art Museum on 27th Street in Billings. It's a compact daypack, about 14 inches tall, with a bright red zipper pull and a small tear at the side pocket from a bike mishap. Inside is my spiral notebook, a blue insulated bottle, and a photo of my grandmother—the bag has sentimental value and I really need it back. There's also a tiny sticker on the inside pocket with a mountain silhouette and a scuff on the bottom; if you found it, email me at the address below.
