This female Humpback literally came right under our boat.  It could have easily flipped the entire boat over if it wanted to but the Humpbacks are gentle, graceful creatures.   All this picture shows is its dorsal fin.  Lisa got some awesome pictures with her camera (unfortunatley it's not a digital).  We may try to get them up on the site anyway.  If not, you'll just have to see them at our place when we get back.  (Wherever that will be and if we ever get back.)
