Lost black messenger bag near Elm Park picnic area in Worcester containing personal items including notebook, pen, and travel mug.

I lost my black messenger bag while walking near Elm Park in Worcester. It contains a few personal items, including my notebook, a pen, and my favorite travel mug. I last remember having it with me at the picnic area and then I must have left it behind when I stepped away for a moment. If found, please contact me - I would really love to get it back.
