Dolphin Video #2

While making this video, I am careful not to fall over the side of the boat and even more careful not to drop  my phone overboard.  Watching the dolphins swim alongside the boat is such a treat that I never seem to tire of seeing them.  I can usually tell when they are following us because of the repetitive splashing sound I can hear from inside the boat. 

Let me know what you think of the video--any tips are appreciated.
