Wedding rings are the most common find.....enraged women tend to throw them into the weeds and then make their husband hunt for them without success. Guys tend to lose them on branches when they're hunting or working with a shovel like your husband. The park I'm going to is snooty Scottsdale where women accessorize to play tennis and volleyball. When they realize they're missing something they just call their insurance adjuster. I know there's a major find to be had there...just have to be methodical about locating it.
