Lost black travel backpack with a small tear and monogrammed tag (J.S.) at the picnic area by Muskegon beach.

I accidentally left my black travel backpack at the picnic area by Muskegon beach this past Saturday. It has a few important items inside, including my laptop and some personal belongings. I remember packing up but didn’t realize I forgot it until I got home. The backpack has a small tear on the side and a monogrammed tag on the inside with the initials 'J.S.'. Really hoping to get it back!
