Lost brown leather dog leash at Waterfront Park, Charleston, SC.

I misplaced my dog's favorite brown leather leash while visiting Waterfront Park in Charleston on Saturday afternoon. I remembered having it when I was sitting on one of the benches, but it seems to have slipped out of my bag when I was packing up. It's a pretty distinct leash, and I'm really hoping to get it back as it was a gift from a friend.
