Lost ring at Mission Bay found

My wife and I were packing our car for a short trip out of state, when I received a call for help finding a class ring at Mission Bay. Sahba was playing a game with her husband and a group of friends two days previous, when her ring came off and disappeared into the sand at De Anza Cove beach.  They all searched on their hands and knees and even using a sifter, but, without success. We met them on our way out of town and hoped for an easy return. It wasn’t all that easy, even though they knew the exact area and it wasn’t all that big. LOTS of iron and other junk made it a slow process. After gridding and cross-gridding, it finally came to light. A pleasure to meet you two and thank you for the reward.
