Blue North Face backpack with pink lining and yellow stitches

I lost my blue North Face backpack yesterday around 3pm near Union Station in Denver. It's a standard 20L pack with a pink lining that you can peek into from the front pocket, and it has yellow stitching along the zipper. Inside there's a Dell laptop sleeve, some notebooks, and a small brass compass keychain attached to the zipper pull. The bag is a bit scuffed on the bottom, but otherwise in good shape. It has sentimental value—my grandmother gave me the patch on the front, and I really need it back as I can't replace the items inside.
