Ooops. I wasn't intending such a long break there between the 'tease' of asking you what the photos were about and then posting the answer. What can I say? Life is busy. So yes, they are humpback whales, cavorting about Bandera Bay. This photo was taken a millisecond or two before the previous post. There are lots more! Near Puerto Vallarta, Jalisco, Mexico. 5 March 2009.
