Jeremy Lezin submitted this photo and note: “I often fly my Carbon Cub SS out over the Monterey Bay, looking for whale activity. I count myself lucky if I find a single whale or a small pod. On this day I flew over half a dozen whales working with a raft of sea lions. The whales would dive down, blow bubbles, and then chase schools of fish to the surface.”
