Lost green hiking rucksack with water bottle holder and extra pockets near the cafe in Sutton Park.

I lost my green hiking rucksack the other day while enjoying a walk in Sutton Park, West Midlands. I had stopped for a break near the cafe, and I must have forgotten it there. It has a water bottle holder on one side and a couple of extra pockets where I keep snacks and a small first-aid kit. If anyone finds it, I would really appreciate getting it back!
