Whales may not be the only thing to be wary of....was surfing reefs between Torrey Pines and 15th street in Del Mar with a buddy when a small group of 3-4 dolphins came in close to us. They seemed to be playing aggressively with eachother when their attention then focused on us. They made several repeated speed runs in tandem pairs right at us with fins out of the water, then making a quick dive under our boards at the last second. The first time we though it was way cool, but in that shallow clear water you could see just how big and close they were. After the third pass we figured it was time to get out of the way but they followed. Couldn't tell if they were playing or being territorial over a female but they were getting way too close so out of the water we went.
