Gray travel backpack with orange zipper pull

I lost my gray travel backpack yesterday around 3pm near the Walmart on S Buffalo Bill Ave in North Platte. It’s a medium-sized North Face daypack with a bright orange zipper pull on the main compartment and a small green fabric patch with a smiley face sewn near the side pocket. Inside I keep a well-worn travel journal, a grey scarf, and a compact digital camera; I’m really hoping it turns up because the journal has notes from my grandmother. The bag has a faded blue shoulder strap and a small dent on the lower corner, easy to spot if someone is looking for it.
