My 21 year-old son was killed by a truck driver while riding his bike to work in San Francisco 5 years ago. He had just moved out of our home a few days earlier. He was the oldest of my 4 sons and such a sweet, positive, charismatic, and loving son. His death has devastated our family. The summer after his death, we just needed to get away from everything and go to be with nature. So we rented a cabin up in the Sierras beside the Yuba River. While wading in the water, the very first thing I noticed was this black heart rock, and it felt like it was from my son, Dylan.
