Lost ring at Equestrian Event

I received a call from Jessica, saying she lost her diamond engagement ring in a stall of a horse barn, while at a horse show.  It was somewhere in the stall with about 2 feet of loose shavings on the floor.  She said she took her ring off to put lotion on her hands, that is when she lost it.  After 20 minutes of searching for it, her husband googled and found The Ring Finders website.  That is when she called me and explained.  The town she was in is close to a 2 hour drive from my place.  I said I would be on my way as soon as possible.  Later I arrived at the barns and met Jessica.  She took me to the stall she lost her ring in.  Her friend was in the stall with a pitch fork, sifting through a mountain of shavings.  I started searching right away.  In no time I had an audience of spectators, all hoping and wishing the ring would be found. Pushing the shavings from side to side with the fork and searching through each pile, the metal detector had been dead silent.  After about 20 minutes of searching through the shavings I got a very loud clear tone!!  A cheer broke out from the spectators, before I even pin pointed the ring.  Jessica was a very happy young lady!
