Black North Face backpack with orange zipper pull

I lost my black North Face backpack yesterday around 4pm near the Worcester Public Library on Salem Square. It's a 17-inch pack with a blue inner lining and some scuffs along the bottom from daily use. The front pocket has a distinctive small orange zipper pull, and inside there's a faded map sticker on the inner lid plus a detachable rain cover tucked in the side pocket. I carry a 13-inch laptop in a padded sleeve, a spiral notebook, and a green water bottle, and the bag feels like a part of me after years of commuting. It has sentimental value and I really need it back.
