Lost dark blue hiking rucksack with hand-stitched patches containing a blue thermal water bottle and hiking snacks at Grand Island Park.

I lost my dark blue hiking rucksack at Grand Island Park while I was unpacking for a picnic. It has some hand-stitched patches on the front and contains my blue thermal water bottle along with a couple of hiking snacks. If anyone has seen it, I would be so grateful to get it back!
