Grey North Face backpack lost near Lambeau Field

I lost my grey North Face Recon backpack yesterday around 6pm outside the Lambeau Field main entrance after the game. It's a 25-liter bag with black zippers and a weathered feel, heather gray with a dark blue trim. Inside there's a small pine-tree keychain on the zipper pull and a folded photo of my dog in the inner pocket. It has sentimental value—my grandmother bought it for me before she passed away. If anyone found it, please reach out; I really need it back.
