Found black messenger bag with compartments near Lake Erie boardwalk containing snacks and a water bottle.

I found a black messenger bag near Lake Erie while I was jogging along the boardwalk. The bag has several compartments and is fairly new. It seems like it might belong to someone who was enjoying a day at the beach. I opened it to see if there was any identification, but the only things inside were some snacks and a water bottle. I would love to return it to its owner!
