My sighting yesterday was free. I saw a pod of dolphins just off the shore while walking on Carmel Beach. There was a whale off the point also. This year, the sightings have become quite common. Whale watching in a boat is thrilling. Kayakers report close encounters all the time.
Yesterday was the first time I personally have been in the right place at the right time. I knew better than to try to capture anything in a photograph with my phone. So, no picture here. You’ll just have to come for a visit. (grin!)
