Update: God's gift to me (and the surfers) this morning

The dolphins came back while I was brushing my teeth.  I thought I'd seen four fins by the pier before, but I only saw three going to and from the pier.  This time I saw three go to the pier but four go back.  I also got a good view of the dolphins (more than just the dorsal fins), and I discovered that they were Common Dolphins.  I got a couple pictures showing the light markings on their sides.  This is probably the best, though I admit it's still not that good.  :o)
