Lost blue backpack with white logo near trail entrance and picnic area in Cameron Park, Waco.

I lost my blue backpack with a white logo while I was out for a run in Waco's Cameron Park. It has a couple of water bottle holders on the sides, and I believe I dropped it near the trail entrance by the picnic area. Inside, there are a few personal items including a notebook and a water bottle. I'm really hoping to get it back.
