Gray North Face backpack with red zipper pulls

I lost my gray North Face backpack yesterday around 3pm. It was on the sidewalk outside the SLO Public Library on Palm Street, near Bubblegum Alley and Mission Plaza, as I cut through downtown. It's a 28-liter nylon pack, about 18 inches tall, with bright red zipper pulls and a blue galaxy patch on the front pocket. There's a small dent in the lower corner from a tumble last week. Inside I had a spiral notebook and my phone charger; it has sentimental value because it's the bag I use for classes this semester. If you found it, please email [email protected]—I’d really appreciate getting it back.
