that was swimming by the dinghy in Puerto Escondido during Loreto Fest a couple of weeks ago. We almost ran over it because it kept changing direction towards us. We were taking a guy out to his boat from the dinghy dock and as he climbed aboard he saw the fins and said "look at the big shark over by that boat!" On the way back to our boat we stopped to have a look and Denny almost was able to pet it but not quite.
