Gray North Face backpack with orange zipper pulls

I lost my gray North Face backpack yesterday around 5pm near Windmill Island Gardens in Holland, MI. It's a 20-liter daypack with bright orange zipper pulls and a small green enamel lighthouse pin on the strap. Inside there’s my sketchbook, a blue USB-C charger, and a water bottle pocket that's frayed at the seam. The bag was a gift from my sister, so it has sentimental value, and I’d really appreciate getting it back.
