Lost black Oakley backpack with distinctive dinosaur and band logo patches near Sarasota-Bradenton beach cleanup event.

I lost a black Oakley backpack while attending a beach cleanup event near Sarasota-Bradenton. The backpack has some distinctive patches on it, including a dinosaur and a couple of band logos. I had some personal items inside, so I'm hoping to get it back. If anyone has seen it or finds it, please let me know!
