My buddy, and member of this forum FlySAR has been providing ring finding service for years in the Portland Metro Area.  As I learned many ropes from him, I became the RingFinder rep for the Olympia WA area before my move to Houston.  Below is the link to a video posted by the Oregonian On-line newspaper on one of his ring finds.  I hope you enjoy the ending as much as I did... Congrats Del, I'm humbled and honored to call you my friend.
