Found black and blue hiking rucksack with water bottle pocket near Birmingham Botanical Gardens.

I found a black and blue hiking rucksack while walking my dog near the Birmingham Botanical Gardens this morning. It was just sitting there on a bench, and I couldn't see anyone around it. It looks like it belongs to someone who enjoys outdoor activities, as there's a water bottle pocket and some hiking gear inside. If you think it's yours, please reach out and describe the details to verify ownership.
