Lost & found backpacks & rucksacks in Central Michigan

Gray backpack with blue trim near CMU campus

I lost my gray backpack with blue trim yesterday around 3pm near the CMU Bookstore on Campus Drive in Mount Pleasant. It's a medium-sized North Face backpack with a small rip at the bottom corner, and a red water bottle tucked in the side pocket. Inside I have a 15-inch silver laptop in a black protective sleeve, a blue notebook with a yellow Post-it note stuck to the first page, and a leather keychain etched with my initials. The bag has sentimental value because it was a gift from my sister when I started college, and I really need it back. If anyone found it, please drop it off at the CMU student center or message me here.
