The Verellen family of suburban Pittsburgh hit the jackpot as three pods of dolphin suddenly showed up alongside our boat in the middle of the York River. As we picked up speed with the wind, the dolphins dove below the boat, crisscrossing without ever touching the hull. All around us, we could hear them breathe and see them blow water. Sometimes they remained in place, playfully jostling each other. They darted too quickly to predict their movements, but there were so many that eventually we caught photos. The shot that got away was of a single dolphin diving straight up out of the water and elegantly falling backward with a great splash. It was an exhilarating show that extended 20 minutes, and then they disappeared into the deep.
