You did the right thing, simple as that!
Hopefully, if you ever lose anything, someone will at least make an attempt to return it to it's rightful owner.
I left a creel lay one time with a bunch of brand new wet and dry flies and other fly fishing gear in it, got home and realized I forgot it and drove back to the place I had left it---GONE!
There was a beige 62 Chevy parked across the road from where I had been, when I got back there it was gone, looked for that car for a few years after that but never saw it again.
I was about 16 then, 72 now, hope that SOB that picked up my creel enjoyed fishing with his find and choked on a fish bone or worse!
