You've maybe seen this already, but it reinforces my thoughts that you just keep stuff. It was also of personal interest because I used to live basically in the same spot. How can the city just keep it and not wait the year, and give it to the finder?
Now, had it been a ring with initials, yea, I'd search the owner. Give it to the cops,,,no way. martin
