In January of 2004, my new brother-in-law, his wife and kids, and my wife and I stood on the deck of a large whale-watching vessel off the coast of Oahu, Hawaii. My wife and I had only been married a few months, and, pre-children, we leisurely-yet-eagerly held binoculars and some sort of camera (our phones barely made phone calls at this point in history, multiple megapixel camera phones being years in the future), scanning the water for ANY sign of movement.
